I've been looking at getting an MX Revolution since it's been getting good reviews. However, I don't like the looks of it and I don't really need all the buttons and thumb wheel either. So I was looking for reviews of the MX 620 which is a bit more stylish and has less features. I've only been able to find 2 user reviews. That's it. Couldn't find any magazine reviews whatsoever. Does anyone have this mouse? Any opinions? How does it compare with the MX Rev?
