That's interesting. I guess if you have to buy a separate card, Firewire 800 is really the way to go. Still, you might get by with the built-in USB 2.
Either way, I love it when people get all passionate about technology like, "Firewire kicks USB's ass 'cause it's more rad!" or "Macs are so much cooler than PC. PC's are for losers!" Oh, wait...actually, I hate that.
