I have that exact keyboard (N800) works great, very portable, folds to just about the same size as the tablet and comes with a nice zippered case. Once you get the pairing down its not so bad, only downfall (on N800 anyway) there's no way to adjust the "repeat rate" with any keyboard's on the IT so you need to be mindfull while touch typing not just with this keyboard but with any BT keyboard. I'm not positive but I believe if you do a search on the forums here I think the 770 might have some editable configurations for BT keyboards that people have posted. Edit: I purchased mine from Amazon as well.
