Well, good to know. Logitech is not what it once was unfortunatly. They have a new CEO though so i'm hopeing things will turn around. Logitech MX revolution? best mouse ever, period. Minor signal issues, and there are some newer technologies it could have benifited from, so the follow on Performance Mouse MX was supposed to be an upgrade. It was a horrible downgrade in every possible manner. One year, they went from king of the hardware heap, to peddling crap. Best mouse button switches in the industry, to cheap plastic chinese knock off switches that fail. Same prices though!
I've not been happy with them recently, and they haven't really released anything "new" except for a few wierd experemental modells in about a year now, which worries me.
