Character Sheet / Tracker would be the first thing.
As I have mentioned before in other threads, my goal is to be able to attend a game as a player with three things in hand.
1. Tablet (with above mentioned character tracker / web access / PDF's of books)
2. Dice (what can I say I still like to roll my own dice, no die rollers for me)
3. Mini for my character
I'm getting closer to this with my iPad2, but cobbled together excel spread sheets for characters is a bit annoying, and just don't seem to run well.
The second program I would look at is an Init Tracker that allowed all the Init actions and had a way to include NPC / Monster stats. I have an app like this that a friend built for me that runs in Firefox on a PC, but I see it working just as well or better as an app for a tablet.
And BTW - this would all be for Pathfinder.
