I've looked into this several times, the consensus seems to be logitech mx900 or mx1000.
I'm going to get a mx900 in a couple weeks, if you ask again around august 12th or so I'll let you know how I like it
My father has a b130. I can't get it to play DVD's using the entire widescreen.
Both Windows Media Player and PowerDVD will play the DVD with a 2" black border all the way around the screen. Top bottom and sides, in full screen...
