ThinkOutside make a USB keyboard that takes two AAA batteries. I am going to try it with my new 770. Kicking myself: 6 months ago I bought their IR keyboard to use with my iPaq.

I can't work out why anyone would want to buy a BT keyboard. Bluetooth drinks your power - all so, what, you can use the keyboard 10 feet from the screen?

I might find if there's a hack that lets me use my IR keyboard with the 770, maybe if I can get an IR receiver that plugs into the computer. Either way, I will report back on how it goes! If anyone else has tried this, could they please post?
