Always, I have an iPad2 and love it. My boss loathes Apple so he bought one made by Toshiba and while he loved it initially, he recently purchased an iPad simply because the graphics were better and it is much faster.
When I first got my iPad I thought it would be great to take notes on in class and since it's so small it would fit nicely in my backpack. Well, it's a nightmare to type on...as is my iphone...and it just isn't very student friendly in that regard. If you want something to watch movies on or TED videos, it's great! I use mine to do puzzles on at night before I go to sleep.
I also recently got one of those HUGE iMac's for my office. It's super pretty and I loved being able to have two screens up at once without having two monitors, but it does not communicate well with the university's PC based operating systems. They just don't speak the same language. So, I went back to my old system but added the new HP TouchSmart 310. And I love it!!
Not switching to the iPhone 5. I don't need everything new that comes out and at the rate Apple releases new products, I'd be broke if I bought the latest and greatest. The new iPad3 is supposed to come out in the spring of 2012!!!
