That's just a whole bunch of gamer talks. Yes it might be true that a 2000dpi or 4000dpi mouse is precise, for gaming. But so what. NONE of the Razor muse are ergonomic! And the side buttons are practically unusable (recessed under the top so it's difficult to press). I know, cause I use the Copper Head and Lahesis at my friends house when we game. Don't like it at all. My own gaming mouse is the Logitech G9 (have to tune it down to 2600dpi, full speed 3200dpi too fast). Who needs 2000dpi for web surfing and Word?
For all around use and carrying around I highly recommend the Logitech VX Revolution. Stylish, rubberize grip is comfortable, nice features when install the control center--custom button assignment. Compact yet provides good support for large hand (palm rest), AND it's ergonomic. I use it myself and have yet to find one portable mouse as good.
