Microsoft is using the mulit-touch technology that they implemented into their Surface Table and porting it to normal computers. Check out the video above of a demo of a laptop modified to use multi-touch.
Will multi-touch displays replace the boring old mouse in the future? I'm highly skeptical, but it looks like enough money is being pumped into the technology that it'll have a shot at the mainstream soon enough.
