Mice have come a long way from the days of dirty and dusty balls that always got clogged up at the worst times to the super futuristic optical mice with the cool looking red-light beaming from the bottoms. Now we have mice with "friggin-lasers", as Dr. Evil would say, that work on pretty much any surface you use them on. The next evolution of mice will extend beyond the basics of being accurate with movement tracking and having three buttons; Logitech is leading the way and their latest product, the MX Revolution is evidence of this.
