I just got in a nice new Microsoft Intellimouse 4.0 and this thing is beautiful, it now has ergonimic finger grooves, the scroll wheel can now be clicked left or right, it's ultra precise, and my favorite thing about it is that the scroll wheel is ULTRA smooth, no clicks at all, just smooth rolling, aaaaahhh.... how beautiful.
Here's a link if ya wanna check it out -
