There was some great innovation that happened at Wildseed. The inverted design made it easy to type with your thumb. The Smart Skins not only changed the look of the device (they wrapped around and clipped on to the body), but there was an Atmel smart card chip embedded in the plastic that would change your wallpaper, ringtones, etc. once it was clipped on. There were RGB LEDs behind each key on the keypad so you would run "visualizers". These could act like a three bar sound meter for your music, for example. Of course, with all of the innovation, what we didn't anticipate was that smart phones were just around the corner...
