The One Keyboard appears to be your regular full-sized USB keyboard with the key difference being that it features a built-in cradle that will house your iPhone/iPod touch. Apparently a press of a single button will allow you to swap between typing on your computer, to typing on your iPhone/iPod touch.
Matias also has two other models available, a Slim One which will feature a laptop-style keyboard and is priced at $80, and a more expensive model dubbed the Tactile One which is thicker thanks to the full Alps-style mechanical keyswitches, along with a 3-port USB 2.0 hub, and will be priced at $200.
