As anyone with Blackberry Thumb can attest, after 8 hours on your favorite gadget, you're dying for a full-sized keyboard. I was never interested until there was Bluetooth wireless technology. (We've written about foldable keyboards before, but none this small and convenient.)

With its unique folding design you can put this puppy in your purse or backpack, yet it opens to a full size keyboard when you need it. Conveniently, it comes with a lap-lock for airplanes or your lap, for that matter.

The Anycome Foldalbe Keyboard supports almost any Bluetooth device -- your smart phone, PDA, Tablet, Media Center PC or notebook, but visit their website for the latest compatibility list.

Product Highlights:
full 4 key rows
up to 60 hours operating time, up to 7000 h standby time
many devices supported
Bluetooth 1.2
supports HID profile

Amazon has it for $111.
