You’ll actually find that USB is what most digital cameras use for device interconnects, these days. Regardless of the advantages of firewire over USB, USB won out. It does not make business sense to sell firewire on the macbook, as relatively few people in the target market for the macbook would have much conceivable need for the port. Those who need the firewire can purchase a macbook pro. If you need to do any serious video editing, why would you want to use a macbook over a macbook pro anyway?
