Best app for ipad

If you have an ipad, what apps are you finding most useful at the moment, and what cases are you finding the best for it.

i just discovered the best app yet for my ipad, called teamviewer, its a vnc app that is free and the best i have seen, works so great even over 3g

also i am trying to decide on the best case for me for my ipad, i want a case that protects it but doesnt scream ipad, but also works well as a stand for typing and viewing movies? any ideas?
