If touchscreen typing just isn't your style -- and slide-out keyboards don't meet your needs -- Elecom's collapsible wireless keyboard just might strike your fancy. The battery-powered accessory can connect to any device that accepts Bluetooth keyboards, and even features a handy fold-out stand for your iPhone or iPad.
When folded up, the keyboard appears to be a little larger than a Nintendo DS, which means it'll probably fit in most pockets, but not all that comfortably. Unfortunately, this sizable typing tool comes with an equally large price tag: US$182. That's a rather steep asking price for the pleasure of typing with both hands, but if you just can't stand composing emails with your thumbs, it might be worth it.
