In Apple's footsteps, Microsoft to introduce their own touch mouse.
The mouse is the result of a Microsoft Research program dubbed "Mouse 2.0".

Great name, as in "We need our engineers to 'Mouse 2' Apple's web site and discover the hardware they'll make next."
I guess we'll see an Arc Trackpad in 2011.
FYI, though I joke about Microsoft following Apple, I do own an Arc Mouse and Keyboard and like them both.
