I finally bit the bullet and went for a mac, and can truly say now that once you've had mac, you never go back! I've got a trusty old desktop which runs XP reasonably well (ok, yeah, it has had 2 disasterous lose-all crashes) and last year I bought a cheap toshiba laptop with vista - which has spent much of it's life "not responding". I'd always thought macs were a little pretentious and arty, and that people who paid that much for a computer had issues...
"Then I saw it's pace, now I'm a believer..."
There were too many people telling me how good they were, and I was fed up ctrl-alt-deleting and still never getting where I wanted to be, so I went for it. Awesome. Expensive yes, but if time is money then I wish I'd done this years ago as I would have saved an inordinate amount of staring at status bars, trying to undo the upgrade or service pack that brought down your system, waiting for task manager to cough and sputter it's way into life because you dared open one too many windows... Nope, from the second I turned this baby on it just WORKED. Out of box, plug in, detect wifi, enter apple ID and we're good to go. A couple of updates downloaded and installed and we're there. Insanely quickly.
Being a mac novice I was a little concerned about getting to grips with it - I'd tried one in a shop and was all over the place! But it guides you through, and after an hour or so it's an old friend. Going back to a mouse seems awkward somehow, unneccessary. It's very intuitive. The battery life is as good as they say, the screen is gorgeous, and everyone who has seen it is "wowed" by it.
What can I say. Buy one now, before you spend another second of your life waiting for windows!!!
