We bring our iPads to the gaming table all the time for our weekly old-school pen and paper RPG sessions. Maps, notes, charts and tables; you name it, ANY game related .pdf we can use in play is made available via the powerful combo of DropBox and GoodReader.
If there was a Strange Aeons list management tool available for the iPad that would be freaking awesome. Especially if it allowed us to share, compare and quickly build a Lurker threat. Ok, a bit pie-in-the-sky the last bit, but I'm just pointing out the potential.
