I <3 my MX1000 as well, although I don't game, I know in windows if you lift the mouse the cursor doesn't jump, but if you bring down the mouse and immediately begin to move it, there is a slight delay, but nothing noticeable during everyday use. I used to be a big fan of wired mouses and all, but I think they really did a good job with this mouse. BTW, the laser is said to be 20x more accurate than the optical sensors. The laser is able to read a much more precise image, again, suposedly, I dunno, feels damn nice to me. The battery is great, mine came charged but I left it on the base overnight, and it took 7 days for the battery meter to show 1 bar. Plus, its damn sexay. Oh yea, I bought mine through amazon via local pickup at my circuit city, and it came up to $63.
