Wow. I recently picked up a lightly used Apple wireless (BT) keyboard through the local Craigslist site. It is a fine accessory to the n800. After the initial pairing, the keyboard is always "ready to go", since it naturally goes into a low power mode instead of turning off.

I certainly am not a fan of Apple products, in part because of being closed source and in part because of product price fixing; but their BT keyboard truly complements the n800.
