The 24 inch iMac screen is preposterously, extravagantly, beautifully large. I plugged it in and switched it on and less than a minute and a half later (I timed it) it was up, working and on line. Simple. Lots to learn, for the software is not quite as intuitive as one is led to believe, but first impressions are definitely "Wow!"
I would say, "good luck with your shiny, new purchase" but you won't need luck. And I had nothing to do with this conversion, I assure you, despite what Katy might think.
Why do I sense that you've been thoroughly Kitchened?
He made me buy a MacBook too. Best thing I've ever bought. It takes some getting used to, admittedly, but only because PCs are so utterly ridiculous - for example, the first time I used mine, I spent ages looking for the start key before it occurred to me that the way to switch it off just MIGHT be to press the on/off switch. Bingo!
Once you've got used to it you'll wonder why you ever bought a PC in the first place.
Hmmm, I hope that you're using Apple --> Shut Down to switch off your MacBook, Katy... I did influence Katy and Mr Angry, but the Doc's purchase was entirely off his own bat...
DISCLAIMER: I own Apple shares.
