Keyboard Buddy : use a QWERTY on your iPhone

Typing with buttons may be more comfortable for people. The Boxwave Keyboard body is for them. It has a container where you place the iPhone. The device literally hugs the iPhone making it an extended slider phone. It makes the iPhone bigger of course when put together. It uses a sliding mechanism rather than a docking station, so when it isn't slided out, it maintains the iPhone form. This QWERTY will go out on December 14 for a pricetag of about $70.
