Digital Home Thoughts: The Microsoft Mouse 2.0 Project

"Microsoft's Mouse 2.0 project is an interesting look at the next step for pointing devices in five completely different versions of multitouch mice. One of the things I liked about the Mouse 2.0 news is that we put our cards on the table at a very early stage and asked what the public thought. Speak up, we're listening."

Here's your chance to give your feedback on upcoming input devices and make a difference in what we'll be using in about 5 years :) I personally think touch-sensitive may be a little difficult to get used to, but perhaps they could improve the concept better. What are your thoughts on the concepts shown?
