This is a quickie concept. A while back I had an idea for a multi-touch keyboard. It was an interesting idea and I'm sure at some point it will become reality. However we're a software company not a hardware player. What could we do in software using existing hardware?
What if you took the essence of that idea and made it as a complimentary tool to your existing keyboards:
The basic idea is that the device connects back to your computer and acts like a secondary display. This would be application sensitive so in PhotoShop you see visual tools on your secondary display and in Word you get editing tools.
