Let me know how you use the iPad2 in game. I'm thinking of having it open to the pfsrd webpage so that I can quickly get info but also having the PDFs of the books on there too (of course) as backup. I'll be curious which I reference more.
I'm currently a player in a game now, but if I were to DM, I would use the iPad to show the players what they were fighting by loading up the bestiary and bestiary 2 and then bring up the picture (making it fully fit the screen) so that the players could see the picture without the stats/name of the monster.
I think it will really add to the tabletop experience.
I was already using the PFRPG App from my iPhone during my game, now that it's also iPad compatible it'll be an even bigger help for getting to stuff quickly.
Mostly I intended to use the iPad for prep and speeding up combat and organization on my end, but I think that I'll go a bit farther and more convoluted with your image idea.
I've already been copying the images of monsters and NPC's from the Curse of the Crimson Throne AP and printing them out on paper (sometimes cardstock from a color lasre printer at work) to show my players. But now I might not need to do that anymore if I can copy the images and import them to the ipad using pages or keynote (which I have for my mac, I'd just need to get the Ipad versions as well)...
At the beginning of Curse of the Crimson Throne I put together a little PowerPoint trailer to introduce the players to the AP. I was planning on doing this at the beginning of each chapter with a Dramatis Personae now that they've met quite a few NPC's. I actually lost the original trailer in a mishap so I think I'll redo it for prosperity's sake.
