New mouse's (mice's?) have been discovered. I’m a lefty so I would probably opt for the one below since I am mousedextrous. 

Blue6000For more information on the new mice and keyboards, checkout the press release at http://www.microsoft.com/presspass/press/2009/may09/05-19BlueTrackPhaseIIPR.mspx.  And you can always get more information at http://www.microsoft.com/hardware/

I have to admit though that the mouse above looks like a VW Beattle compared to the R8 just below it.  The Audi R8 is hot.  Can we get a Bluetrack R8 mouse?  Grin.
