I'm looking to maybe replace my mouse, and I quite like the look of the Logitech G3 mouse, mainly because it looks like the same design as my trusty Wheel Mouse, but with a couple of side buttons added. The problem is that according to the Logitech site, the software is PC only, but I assume that the standard left/right/middle buttons and scroll work as normal. I've read in another post here about the MX518 that although the extra buttons on that mouse can't be programmed in the control panel (except for expose?), they work fine in other applications (World of Warcraft was mentioned, and it's that I'm specifically interested in). So, anyone actually used one of these mice? Or should I just get the MX518? Thanks .
