Exactly. If I let it sit on a desk, it times out and then I need to hit the power button to wake it up. But this behavior doesn't make sense in the context of mobility. If you shove the thing in your pocket, it will never timeout since the repeated screen touches will cause the n800 stay awake.

I'm thinking that locking the screen and keys should truly do exactly that. Or maybe a long keypress on the back button (on the home screen) could put it to sleep....
