the mouse looks pimp but its pretty small so u'll be moving it around with ur fingers the whole time. the logtech mx518 is big and fits the hand very well. id switch the mice...
and those, im pretty sure, will come with a usb>PS2 adapter so the usb 1.1 isnt a problem
I bought a diamondback(salamander red?) over the weekend, sort of didn't like the shape after using it, so I took it back and picked up a G5 for 10 bucks more.
Other than that, it's a nice mouse, though. It has 2 buttons on each side that you can program to do stuff - I really couldn't be assed to click the right ones with my pinky, however.
I'd consider going with an MX518(It costs less, anyway) unless you're left handed or something.
I have that mouse, its nice takes awhile to get used to though and the extra buttons are too low down. Id go with logictech mouse wish I would of now...
