The only wireless mouse that doesn´t totally suck is the MX1000 and I would say it would be worth trading a MX1000 for one of those new 1600 dpi mouses
I just got this mouse and I'm very happy with it. It's taken a little getting used to from my old 5 button MS mouse, but I like it. Very smooth and accurate.
Do you guys install the software it comes with? As a general rule I never install mouse software, but I wasn't sure if it included things necessary for the mouse to reach its full potential. I can adjust the DPI on the fly without it so I figured it wasn't necessary.
