I not only adjusted to the Boomslang but found that other mice were becoming increasingly more difficult to use. High sensitivity is where it's at, and other mice just can't compete anymore. In the end all that matters is your frag count. The Boomslang's got you dialed in. Take out the boss before the minions.
Increased sensitivity is a plus in any game.
In Windows, the advantages are not quite as obvious. Working in image applications where exact placement is necessary, the Boomslang excels. Where I was picking up my Logitech to get it re-centered on the pad, I'm now moving the Boomslang an inch or less. I almost never have to pick the mouse up. 2000 dpi does have its benefits.
