Why not...![]()
This looks interesting, but I'm quite skeptical about its practicality.
In particular, I'd worry that any large touch screen area (like this, or the rumours of the "strange touchpad") would be subject to lots of accidental contacts that would send stray inputs to the system.
If the "palm rest" is multi-touch, where do you rest your palms?
It also seems that the ergonomics of the keyboard would be at least as bad as Apple's regular keyboards, and the lack of tactile feedback would make typing difficult. (Although if it's software, it should be able to be a curved keyboard, or a Dvorak, or anything else - whereever you put your hands is "home row".)
