I am getting my first internet tablet soon. However, i need some help in getting the various accessories to go with it.

Firstly, i read that i will need a powered-usb adapter to use it as a host device. Which one would i need? I know that right now usb host mode is still not stable/possible, but i'm betting that it'll work.

Secondly, i need to know a cheap bluetooth keyboard that is compatible with it.

Thirdly, how long will the battery last on a N800 when using it with a bluetooth keyboard? I'm planning on using it for programming.

Lastly, what screen protector should i get?

Thanks in advance!
