iFrog one-handed Bluetooth keyboard

FrogPad iFrog

The Gadgeteer has a review of the iFrog, FrogPad's Bluetooth-enabled one-handed keyboard. You may be better off getting a proper folding model or just buying a PDA or a smartphone with a built-in keyboard (we've heard that they do exist), but the reviewer says that the big reason to use one rather than a regular keyboard is that you can type with one hand (it comes in lefty and righty layout models) and use a mouse in the other. But after three weeks of hardcore usage (as the primary keyboard), the reviewer only managed to type 20 words per minute, way down from his usual 55 wpm using a regular keyboard. Battery life was an excellent two weeks of daily usage, but there is no battery level indicator and the iFrog itself is a whopping $225.
