Last year Microsoft showed off the Surface and today the firm presented a big TouchWall computer:
I'm not sure whether Gates is getting more emotional, but he is definitely big on the power of new user interfaces, especially touch-screen devices. On Wednesday, he is set to show off Microsoft's latest prototype, known as TouchWall.
The device to be shown Wednesday is something like a giant Surface unit turned on its side.
TouchWall is one of several multitouch prototypes Microsoft Research has created, in addition to the tabletop unit that Microsoft's Surface group has begun to sell commercially. Among the other devices the company is also reportedly working on is a sphere-shaped device.
