"Logitech began their rechargeable 'cool' line of products with the MX700 mouse. Logitech wanted to innovate something different by keeping people from replacing batteries. MX700 was an awesome mouse, however it lacked those gaming features that people needed and MX700 mouse was never really a gaming mouse from the start. Then Microsoft began releasing their Bluetooth line of products and then we suddenly saw MX900 which was even farther away from a gaming mouse. Of course that didn't stop Logitech, in 2004 they released MX1000 laser mouse that revolutionized the way mice work. It offered 20x more tracking power than older optical mice with a resolution of 800dpi and 5.8 megapixels/sec. This new upgrade offered the product line to be finally used by gamers. Of course MX1000 was not the best gaming mouse from Logitech, they had to again come up with something better. It is something called G7 Laser Cordless Mouse that offers unprecedented features and precision. Logitech call!
s it 'extreme cordless performance' and it is certainly true with 2000dpi laser that churns images at 6.4 megapixels per second."
