I have been an Apple fanboy most of my life, and I’m slowly coming off of it. I had a Mac since I was like 5. I use all the iDevices. The closest I get to PC is dual-booting my Mac so I can play PC games.
That being said, I definitely do think Microsoft has ripped off a lot of Apple’s ideas. And so has Google with Android. But Apple has ripped off a lot of ideas too - even their first revolutionary windowing system was a ripoff of a Xerox invention. Employees who work at any of these big tech companies often work for many of the others. In short, it’s all an incestuous orgy and it’s all going to evolve together as a result.
And I don’t really use my iPad 2 very much, but my wife is on it all the time. She gets recipes, watches HBO / Netflix, etc. etc. It’s a great device to have floating around the house for quick media consumption. I also set it up to watch a movie when I have to wash dishes or do laundry or some other menial task. Then I can very simply carry it around with me as I move into different rooms. Good stuff. With a laptop you can do many of the same things, except the added bulk of the keyboard really is frustrating and makes much of this impossible (can’t just place it on a shelf or something). Plus, many laptops will be completely and totally destroyed from just a dab of water. Not so with iDevices, which are close to water proof (I mean that just in terms of getting random droplets on them, etc. you certainly wouldn’t want to bring it in the shower).
Anyway. Windows 8 moving more towards tablets is unsurprising. It is clearly where the market is heading. I prefer tactile feedback (keyboard) but they’ll figure out a way to give us that too, don’t worry.
