So, I just got my new iPad 2 and synched my stuff last night. I started trying my apps out, and right away I could see that some of the apps for my iTouch were not compatible (or so I thought) on the iPad. Example: I have both versions of Angry Birds on my iTouch. When I opened the App on my iPad, it was small and the same size as on my Touch. So, my husband went online to look up how to make it work. My husband is very much all things "Apple" challenged. I should have "researched" it - my mistake. Remember, I am only 1/2 hour into owning this iPad. I thought it was just an oversized iTouch - my mistake again. The "answer" he found said that there were HD Apps I needed in order to play full screen on my iPad. I later found out this was not the only correct answer . . . You do not have to buy new Apps for everything. It was only minutes after I paid for the HD App that I found the zoom button to make it full screen, it's just not in "HD". I guess you call this a learning curve . . . .
