pdf options are excellent on ipad. its possible that ipad 3 might be slower than ipad 2 if it uses the cpu to decode and has to draw retina graphics
Hmm, I hope thats not the case (being slower). But I did call my local Apple Store, and they said that there will be 8 stations set up with the new iPad. And most likely there will be pdf reader (with files) to try it out. I plan to go on Sunday, hopefully it still wont be too busy.
