So I have a wireless MM that I bought shortly after it was released and it has gray buttons on the side like this:
The right-click doesn't work very well, so I stopped using it.
When I bought my iMac, though, it came with the wired MM that has white buttons on the side. It works flawlessly in every way. Do the newer wireless MM have white buttons, and if so, is this evidence that they work better?
