I own three of the older N50s. When I upgraded to Vista I had to use a registry hack to get it to work. When I upgraded to windows 7 I did not need the registry hack. The directional thumbpad on the n50s is pure genius and I cannot play without. AA few months ago I picked up a G13. While it has more keys than the n50 I just couldnt get past the thumbstick. The G13 uses a thumbstick which is constantly resisting your thumb always trying to go back to the center position. I used it for 40 hours before I went back to the more comfortable nostromo n50.

Here is the registry hack http://www.sevenforums.com/gaming/10...peedpad-3.html
