I looks like we may have a 'war' between firewire and usb2. I hope usb2 wins because it is faster, easily good enough for digital video, so digital audio is a breeze, and backwards compatible with the all the current usb1.1 equipment.

A card for your pc is cheap and only needs a spare slot. I got a usb2 pcmcia card for the laptops. More external soundcards and DAW are being made that use usb, so maybe this will something we will see more of in the future?

The advantage of an external usb soundcard is you take the a/d and d/a away from all the high freq digital crap inside the pc.
