I have two fast scsi-2 harddrives (one at 10 and the other at 20mhz), and while they're not the greatest (Fireball and Lightning by Quantum hehe), I'm pushed to get more than 5mb/s (and I've enabled sync and wide negotiation) when copying from one to another. Although I do agree with you, and would prefer to use a dedicated scsi bus, I think that USB could be more useful than for both mice and keyboards. If I wanted something I could chain mice and keyboards onto I'd use a PS/2 port. I think USB could also find use for such hardware like sound devices, faxmodems, and scanners (they are rarely used ya kno?). Regardless I don't have the $$ to care about switching to USB anyways. - alex
