I got two generic keyboards and both seem to work fine. I got this one for when I'm at home and this one for my completely mobile setup. It seems like any Bluetooth keyboard should work. But if you end up getting multiple generic ones, it seems like they're going to just show as "Bluetooth Keyboard 3.0." That's what both of them read to the Supernote.

The first one I got because I just needed something overnighted, but it works just fine. I haven't used the second one too much yet, but that's because I just got it today and I haven't been in a situation to really use it too much yet. I just wanted a second folding one so that way I don't have to take up too much extra room with the first one I ordered.
