Firewire 400 at the time worked a heck of a lot better, but then apple had to have a very high royalty fee. FW still works better, but you see where it is in the new designs now even at firewire 800. You can't buy anything today with a FW port on it. I hope those holes in apples feet aren't too painful, but never would I ask for them to be painless either. Like John Wayne said, stupidity should hurt. Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
