Heyyo,
USB2 isin't a complete project? you mean, it's supposed to get even faster? cool, plus USB2 ports are backwards compatible to USB1.. so if they do make something like a USB3 port, I bet I'd be the same deal. For me, I think that wireless technology is still in development, cause I think the fastest wireless router is only 48mbits is it? well, something low like that...
But what I was wondering for usb keyboards, is if it supports more buttons to be held down at 1 time. I think the max for PS/2 keyboards is 3-6 is it? I dunno... but if anyone has a USB keyboard, plz tell me how many buttons you can hold down at once.. If it's more than a PS/2 keyboard, it's already better by half the usefullness of a PS/2 keyboard. (if you ask my why? sometimes me buds are too lazy to bring over comps, so we just cram all together on 1 keyboard n' mouse, n' a gamepad playing serious sam 1 & 2 it's annoying when your buds purposely hold down keys to make you fall into pits. Makes you wanna hold down a lot of keys when keelers are running at them.

)
I don't think there's too much advantage to Mice though, unless the new laser technology requires more bandwith than what PS/2 provides. I know optical mice seem to do good on PS/2 (but not my crappy mouse.. don't buy that turbo gamer (aka. mitsuko) keyboard n' mouse combo... I warned you.

).
