Touch me there… and there.

You probably know about Single-touch screens.  If you have ever used a SmartBoard, Tablet PC or any other sort of touch sensitive device you will probably have noticed that you can only have a single point of contact.  If you try and draw on a SmartBoard in two places at once, it takes an average of the two locations and draws the line halfway between the two contact points.  Getting used to writing on a SmartBoard without touching the screen is a bit disconcerting at first but most people pretty quickly adapt.

Likewise, the reason that you can't write on a Tablet PC with just your finger and why it requires a stylus pen is that it's really the only way to give the screen a single contact point, allowing you to interact with the panel using the stylus tip while having it ignore the rest of your hand resting on the screen while you write.  Basically, most of the touch devices we are familiar with will tolerate a single point of contact only.

So what we really need to move forward is a multi-touch screen.  I was rather impressed when I first saw Steve Jobs introduce the iPhone at the last MacWorld Expo, especially the way he was able to interact with the screen by touching it in more than once place at a time.  The shrink and expand gestures for images were particularly fascinating; the way you can resize an image by stretching or pinching it with your thumb and finger.  Very cool stuff.

Apparently the  multi-touch technology was developed by a guy named Jefferson Y Han.  You can see a video of the touch screen technology being used here... watch it all the way through, as it starts off with just arty farty stuff, but gets into some very interesting deveopments with the image handling...

Apparently, it seems that Han originally developed the technology and was approached by Apple to go work for them, but he declined.  Seems like Apple managed to licence the technology from him though for use in the new iPhone.  I don't really know any further details of that deal and I'd only be speculating if I tried, but it certainly seems an interesting development and one which could bring some cool new ideas to the traditional user interface over the next couple of years.

The World According to Steve Jobs

I have a great deal of respect for Steve Jobs. As one of the founders of Apple Computer, Next Computer and Pixar Studios, I think he's a pretty amazing guy and his impact on the world via his contributions to the computer industry are huge.

If you're interested to hear what advice a guy like Steve Jobs might give a young school leaver when it comes to life and success, then you might enjoy watching this video of Steve giving the commencement speech at Stanford University last year. In it he offers his thoughts about what matters most in life and what success really means.

What I thought was interesting is that he was not saying the things that "the system" promotes, namely go to school, get a good education, get a good job and work hard for the rest of your life. Instead he talks about diversity of learning experiences - connecting the dots, as he calls it - and how learning should be for life, in areas that fascinate you, about things which make you passionate. His message is that life is way too short to spend doing things that don't make you excited every day.

One Fast Mac

I bit the bullet and bought an extra Gb of RAM for my Macbook Pro yesterday, bringing it up to its maximum memory capacity of 2Gb. It's a pretty fast laptop anyway, but I was finding that when I had a lot of big programs open, and particularly when I was running Windows using Parallels, it would occasionally have a bit of lag when switching between running apps. Not any more...

The extra gig makes a big difference to the way that non-Universal apps run. Apparently there is a fair bit of memory overhead required for Rosetta (Apple's built-in emulation layer that enables applications written for the PowerPC chip to run on the new Intel-based Macs), and even with the Macbook Pro's standard gigabyte of RAM it works the machine hard to run Rosetta apps such as Office and Photoshop.

For anyone using a new Macbook or Macbook Pro, I'd suggest seriously thinking about adding that extra gig. I'd say it's definitely worth it, although you ought to shop around as the aftermarket memory from places like Crucial seem to be much cheaper than buying memory directly from Apple.

The ads just get better

They've been out for a little while now, but just in case you haven't seen the three new Mac ads, they are worth a look.  Very, very funny.

Crossing Over

I've just been playing with a very cool piece of software for the Mac. Or is it a piece of software for Windows? Actually, it's kind of both.

Crossover is based on the work of the WINE project - a curiously-named self-iterative anagram that stands for Wine Is Not an Emulator. WINE has long been used in the Linux community as a means of getting Windows programs to run under Linux. When I first looked at it several years ago it was still very raw and new and difficult to use. However, in the last few years, WINE (and in fact Linux too) has come a very long way. Linux development moves forward at an amazing pace and the last few distributions I looked at were very impressive indeed.

Back to Crossover. Although it's still only in Public Beta, Crossover runs as an application on either the Mac or Linux platforms and it allows genuine Windows applications to be run natively on either of those OSes. Not emulated. Natively. That means you can take a Windows program and install it on the Mac (or Linux) and have it run as just another application under Mac OSX. It works by translating the API calls of the Windows app directly to the equivalent API calls in the Mac OS, effectively allowing the program to exist in the new OS environment. It's an incredibly clever piece of software engineering that I think is greatly significant for those of use who don't want to be restricted in our choice of operating system.

The neat thing is that it truly does run the program under Mac OSX, so the speed of the programs is pretty much the same us it would be under Windows... it's not an emulation like Parallels, and it doesn't require a reboot like Boot Camp. It just runs the program in OSX as though it was in Windows. You can copy and paste between the two environments, and the Windows app has full access to the Mac's file system. The application toolbar resides in the window, just as it would under Windows, while the Mac toolbar shows the Mac as running Crossover... very neat! The installation was very straight forward, and sports a long list of supported Windows apps, including several versions of Photoshop, several versions of Office, plus a bunch of others, including games. You can also try to run other Windows apps, but obviously they can't test everything. I suppose that's why it's still a Public Beta.

It's kind of weird seeing Windows apps running on my Mac. I don't really have a need to do it, since there is a Mac program to do do pretty much everything I need to do. I suppose it would be good for software training, as you can effectively use one machine to run an application for whatever platform you need. Other than that, I'm not sure why I'd even want to run a Windows app on my Mac. Still, it's pretty cool that it can be done, and opens up a whole range of options for those people who would really like to switch, except for that one Windows program that they just can't live without...

We live in interesting times.

Sensing that Spirit

My daughter Kate and I went to the Sherway Gardens shopping mall in Toronto on Saturday morning to check out the opening of the new Apple Store. Apple Stores are somewhat of a novelty for me, since we don't actually have any in Australia. (What's the story SJ? Aussies want Macs too, you know!)

Apple Store, New York City.  Click to Enlarge

Since living in Canada I have visted the store at Yorkdale Mall in Toronto, where I bought my MacBook Pro, as well as the store in Galeria Mall in Cambridge Boston, where I had to buy a replacement power adapter for the one I left in a hotel in Sydney, Nova Scotia. (I eventually got that power adapter back btw). I also visited the very cool and funky Apple Store in Fifth Avenue, New York City when I was there last month. These stores all do basically the same thing - let you try and buy the whole range of Apple products.

The funny thing is that the product range for Apple is quite finite. The do a couple models of MacBooks, a couple of desktop models, and about 7 different iPods. There's also the accessories and software and various bits and pieces. It's a wide range of stuff but it's not so big that it's mind boggling. And every Apple Store looks more or less the same, has the same sort of feel to them, and has the same products on display. Prices are fixed by Apple so they don't really do discounts or special deals. The just sell and display the whole Apple range.

So why did I bother going to the opening of the Sherway Store? I knew I wasn't going to see anything I hadn't already seen. I was pretty sure the pricing would be standard (not that I planned to buy anything anyway). The offer of a free T-shirt to the first 1000 people was kind of cool, but hey, a T-shirt is a T-shirt right? The reason I went was just to check it out, "soak up the vibe" and be able to say I'd been to an Apple Store opening.

Well, the store opened at 9:30 and we got there about 9:35. As we approached the store, the line to get in stretched back down through the mall, out the doors, across the plaza and into the carpark. It was probably 400 metres long. It took us nearly 40 minutes to get in the door, and when we did we got a T-shirt, spent about 20 minutes looking around (at products we'd seen many times before) and then we left. With any other store, I would never have waited in a line like that, but somehow, Apple seems able to create a buzz, a hype, and a sense of wanting to just be a part of that. I don't quite know how they do it, but it's very real and the sight of the long line of people waiting to visit the new store was just a testament to Apple's ability to somehow draw people with that indefineable spirit that only Apple seems to be able to generate.

Steve Jobs once touched on it in an interview when talking about Apple's early products...

"It's the same thing that causes people to want to be poets instead of bankers ... And I think that that same spirit can be put into products, and those products can be manufactured and given to people and they can sense that spirit."

Interestingly, there was a Dell store not 100 metres away and it was totally deserted. Not a single person even browsing. I guess people can sense Dell's spirit too.

The Anatomy of a Good Decision

I started using a personal computer in 1982. It's now 2006, and for the majority of the past 24 years I've used computers running some version of Microsoft Windows. My first experience with Windows started with version 3.0, then 3.1, WfW, 95, 98, 98SE, ME, 2000 and XP. On the server side I've used Windows NT, Windows 2000 and Server 2003. I have also been a Microsoft Office trainer, hold a Microsft Office Specialist certification and have even been a technical writer for Microsoft. Professionally, I'm currently responsible for managing a Windows network that encompasses 6 Windows servers and around 300 Windows XP workstations. You could say that I have invested a good deal of time and energy into Microsoft products over the years.

So when the time came recently to buy myself a new computer, it may seem surprising that I bought myself a Mac. Yes, a Mac.

It's not my first Apple. I started my love affair with personal computers on an old Apple IIe, back in the day when if you wanted your computer to do anything useful you often had to write the software yourself. I also had an old Mac SE30 that I used to just love working with, and even an LC575 back in the old System 7 days. But that was ages ago, and I've pretty been in a Windows world now for the past 15 or so years.

So, after all this time, why another Mac? Because when the time came to fork out the hard earned cash to by a new machine I wanted to best computer I could get. I wanted great performance, rock solid stability and value for money. Do the research and you will probably come to the same conclusion. For me, it had to be a Mac.

The decision to switch was not taken lightly. I put a lot of thought into my decision to be a "Switcher", as Apple calls us. I had a great deal invested into the Windows platform, both time and money. All of my software was for Windows, all of my expertise was in Windows, and to be honest, I was comfortable in Windows.

What I wasn't comfortable with was the endless stream of viruses and malware that seemed to be attacking the Windows platform on an almost daily basis. I wasn't comfortable with the inordinate amount of time I seemed to be spending maintaining my computer just I could use it to be "productive". I wasn't too comfortable with the way every Windows machine I ever used just seemed to slow down over time, to become more and more sluggish until it ground to a useless halt and the only solution was to reinstall the OS. I was very uncomfortable with system freezes, application crashes, and a system that clearly was not able to cope with the not-unreasonable demands I was expecting from it.

There is an old joke about a dog laying on a wooden verandah floor, howling in pain every few minutes. A man comes by and asks the dog's owner, "Your dog appear to be in pain. What's wrong with him?" The owner explains that the dog is laying on a nail which is sticking out of the floor. The man then asks the obvious question, "Why doesn't he get up and move?" The owner replies, I guess the pain just ain't bad enough yet."

For me, the pain of Windows just got too bad. It was time to get up and move.

I made a list of all the things I used my computer to do - from basic word processing, to video editing, to webpage development. I admit, I like trying new software applications and I had a lot of applications on my hard drive, some I only used occasionally and others i used all the time. I listed the tasks - not necessarily the actual applications - that I used a lot and then started to research what alternatives existed in the Mac world. For the tasks that I use my computer for, there was not a single application that did not have a Mac replacement that wasn't equivalent or better than wat I currently had under Windows.

To be fair, the Mac version of MSN Messenger, which I used a lot, was greatly watered down compared to its Windows cousin. iChat looked great, but most of my friends use Windows so it was not greatly usful to me. Skype was good on the Mac, but lacking live video like the Windows version. Other than that, I had alternatives for just about everything else I needed.

I spent ages looking through the Mac OS X tutorials on the Apple website. I use my computer a lot and I wanted to to be totally sure a Mac would work for me. Would I like the new interface? Could I deal with the Dock? The switch to a new user interface for a new operating system seemed like such a big deal! I had Macs before and really liked them, so I don't know what I was worried about, but I was. I think it was all about having so much history tied up in the Windows OS I knew so well that the decision to switch seemed so much more important that it ought to have been. I'm sure that's what keeps many Windows users where they are... the fear of the unknown and the new.

Logically, I couldn't help thinking that if the Mac OS was anywhere near as good as the user experience I had been enjoying with iTunes and my iPod, then it would have to be pretty good. I mean, if Apple could do such an amazing job with those two things, then why should OS X be any different.

Still, I vaccilated on the desicion. I went to the Apple Store online so many times, loading up my shopping cart with the newest MacBook Pro, only to hesitate when it came to clicking the buy button. I just wasn't sure that I could throw away everything that I'd worked with over the past 15 years. I watched the videocasts from Mac World and listened to Steve Jobs go through all the cool new features of the current models. I read article after article, blog after blog, review after review, but I just wasn't quite sure I was ready to finally let go of that Windows lifeline and officially become a "Switcher"...

And then a wonderful thing happened. My Acer Tablet PC broke. Now I had to get a new computer, so I bit the bullet and did it. I bought a MacBook Pro.

That was about six months ago, and all I can say is why did I wait so damn long! When I sat down to write this I was going to make a list of the five things I liked most about my Mac and the five things I liked least. You know what? I can't even think of five things I don't like about my Mac. I can't even think of one thing I don't like. To me it is, without argument, the best computer I have ever owned. It does everything I could have asked for, and more. The interface, the user experience, of Mac OS X is so far ahead of anything else I've used, there is no competiton. It's sleek and sexy on the outside, it's an absolute joy to use on the inside, and the stability of its Unix heritage under the hood makes it, for me, the perfect computer.

I feel like I finally have a computer that works the way I work. I don't have to think about how to make it do stuff, it just does it. It doesn't fall over, it doesn't crash, it doesn't require me to be "the computer guy" the keep it running, it doesn't need to be restarted all the time or to be updated all the time, it's fast and stable, it lets me do all the things I like to use my computer for.

To use a well worn Apple cliche, it just works. Thanks Apple.

This product will be great… one day

Just as a follow on to that last post, it's interesting to compare the marketing strategies of Microsoft and Apple, especially when it comes to the release of new products.

Microsoft takes the hype-it-up-early approach - witness such products as Origami, Vista and Zune. Apple on the other hand are very tight-lipped about new products and essentially say nothing until a new product is announced by His Steveness at an event like MacWorld or WWDC. This latter approach by Apple always seems to cause the rumour mills to work overtime with speculation and guessing at just what might emerge, but the actual product releases often exceed consumer expectation, or at least are still full of surprises. On the other hand, Microsoft's hype-in-advance approach seems to build enormous consumer expectation around their products but it is often dissapointingly not met when the crunch comes.

With both Vista and Zune still out on the horizon somewhere, it will be interesting to watch and see just how they manage to meet the expectation they have created for themselves. It appears that in Vista's case the only way they will be meeting their long-overdue launch date will be to water down or eliminate features... and many of those features are ones that OS X Tiger already has.

Zune is still a ways off and is being touted as an iPod killer, but with over 75% of the portable music player market it will have a lot of catching up to do. And now Sandisk is talking about having an 8Gb flash memory based player, filled to the brim with features at a competitive price.

I can't help but think that the key differentiator is not just about features but rather usability, and the others have a long way to go to catch the iPod in that regard. Not only that, but it's only a matter of time before Apple (and others) have access to 8Gb flash memory, and with the profit Apple makes on iPods, they can still afford to compete.

Bring it on...
