My last few sessions i have been using Hero Lab on my Motorola Xoom via Microsoft RDesktop connecting to a background session on my PC back home. It works well, and with multiple sessions set up, each person at the table can have their own copy of hero lab running. Not as great as a native app, but it covers my needs for now. So great when towards the beginning of the first session with this setup, I took multiple ability drains, ability damage, and level damage. Hero Lab made dealing with that a breeze - would have sucked to have to do all those mods manually on a paper sheet.
