Works fine for me too. The only issue I have is that I don't usually keep BT on on the N800, and with an external device you're bitten by that mis-feature where you have to go down the control panel to re-enable BT (ideally the icon should stay in the status bar and it should have an 'enable' option). This isn't a problem for when the N800 is the connecting part (as in BT DUN), as it enables BT automatically. For keyboards it's another story.
