The only way I would like it improved is to give it a retina display. High rez pictures on an iPad with that would be stellar!

I echo John's sentiment about the cameras too. In the two months I've had my iPad 2, I've taken maybe two pictures, tops. The pictures in question were pretty disgraceful, now that I think about it (Apple should be ashamed to put such awful cameras in what has become a flagship product), but at the end of the day, I can't see cameras becoming a serious issue for the folks that bring us updates.
