Gen 1 iPad App Suggestions?

I have a 1st generation iPad just for this week.  Work had some leftover from a trade show or something and they gave 1 to each of the main groups to test out for on-call to see if it would work out.  Since I'm on-call this week I connected into work with it today and it's ok, but really not a worthy laptop replacement. 

Anything I should be sure to try while I have it as far as apps/games/cool things go?
