I too have been very pleased with the iGo XTBT01. Once synced, it remains so (although the first character you type after it has fallen asleep takes a couple of seconds to register).

Small size when folded, nice zippered leather case included, reasonable typing speed.

One nit on the keyboard: If you're a command line user, the up-arrow key is where the slash should be - so you'll tend to regress commands when typing paths. :-)

One nit on using any Bluetooth keyboard with the N800: When in "off-line mode" (to save power when not using WiFi), Bluetooth is also "off-line" and the keyboard doesn't work. I'd prefer to control Bluetooth and WiFi radios separately.

But those are small nits compared to the convenience of a good portable keyboard. Definitely recommended.

I use my Apple bluetooth keyboard.

I use the Apple Bluetooth. There are MINOR connection issues. All I do is disconnect the keyboard via the quick menu at the top of the screen. Then it reconnects in seconds. Otherwise it is excellent.

im planning to get the targus foldable usb keyboard.
will it work wit the n800?
of coz im getting the otg adapter too..

I use the Apple keyboard and have had 0 connection issues. I just turn on the keyboard and it automatically connects. This is with my 810.
