a lot of the cheaper wireless mice lag, but from what I have read, the MX1000 doesn't
if you want to go wireless, Logitech is by far the best IMO
at work experience, the PC store was really impressed with me, so I got a free Creative wireless mouse and keyboard, 400MHZ Duron processor, 6GB Laptop Hard Drive, and an IDE and floppy cable
the Creative wireless mouse is not bad, it is a lot better than that crappy ball mouse I got to begin with, but it does cut out and lag occasionally
