I was curious enough to pick up a Logitech board to see how well it performs for mainly simple note taking and web surfing. I actually like it enough to keep it as it looks and feels of good quality and types great. It's blue-tooth only and paired up instantly. The best of all keyboards? Not sure on that but works great on the Nexus 7. Retails for $60 and can be picked up at your local b/m store.
Oh yea, and a plus is that the keyboard slips into a case (only for the keyboard) that can also be used as a stand for the N7.
