I was able to take Verbatim's Mobile Wireless Bluetooth keyboard for a spin. This is a revision to an earlier model they have. In the package, you get their keyboard, batteries, case, and guide.
This keyboard reminds me of the days when I was using a ThinkOutside and Palm Wireless keyboard with my pocket PC's. This keyboard folds in half when not in use and can be placed in the included carrying pouch. It is a little thick when folded in half but none the less, it's still pretty compact and easy to store.
