I will probably be returning mine, although there is quite a lot i like about it like the size and light weight considering its size, and the speakers are pretty good too but not amazing like a lot of people are saying, they are just very good for a tablet.
The two main reasons i may be returning it-
1) Screen quality not as good as i was expecting, it has one of those overly bright white screens that strain your eyes and at the same time make the colours look a bit washed out. I would prefer one of those screens that has a slight yellow tint to them that make the colours look lot richer and warmer and are easier on the eye.
2) iOS is just not very good, its much better on a phone which is what it was designed for, OSX is just so much better so i will be sticking with my Macbook Pro. Also Apple haven't bothered to optimise anything about iOS for the iPP, all that extra screen space not being used, they should be ashamed.
