As a new PowerBook owner I'm interested in buying an external mouse for the times when I'm not taking advantage of my newfound portability. I don't know much about mice but have heard that BT wireless mice tend to have a bit of delay between rapid movements. Now I wouldn't classify myself as a "gamer" but I do ocasionally play and old game or two (Diablo 2 comes to mind) and would probably be annoyed by this delay. What's the story with RF mice like the raved-about Logitech MX1000? Do I need to plug a receiver into a USB socket? Is this clunky when used with a PowerBook? Does this have the same delay problem that BT mice have? Wired mice. As a last resort does anyone have recommendations for a great, precise, quick, multi-button wired mouse? Thanks in advance.
