Well, I dont know about that. USB2.0 is faster than WireWire, at least for the moment. Most of the articals that I have read on the subject talk about how great USB1.1 is and how vastly diffrent FireWire is from USB. Then they talk about how USB2.0 may befast but its, toolate, toolittle, too slow. FireWire has dug in foxholes in the DV world and there is just no need for a USB2.0 intelli mouse. FireWire 2.0 is just arround the corrner and will crush USB2.0. If USB2.0 gets cheep enuph, we might just see the replacement of USB1.1. But FireWire will rule the DV world.
OK, I'm working from memory here, so don't flame me too badly, but I read a litany of articles around the time USB2.0 was first announced by Intel (they announced it way early, years ago, to counteract the growing popularity of FirwWire. Now, there may have been technical hurdles that they crossed with USB2.0 since then, but at the time, as I recall...
...people were saying that while it's true USB2.0 had a theoretical maximum throughput greater than that of FireWire1 (480 to 400), in the real world USB2.0 would rarely perform better than FireWire, because the device chain is polluted with all of these backward-compatible USB1.0 devices which would lower the overall speed of the bus back to the USB1.0 speed limit.
Can anyone confirm if this is still true? (That if you have a USB1 device attached to a USB2 chain, your USB2 devices operate at USB1 speed?)
Also, I remember reading that when you have non-powered devices connected to a USB chain, it degrades the performance of the entire chain.
The end result of all this was that DV cameras and external hard drives would perform much more inconsistently on USB2.0, whereas FireWire1 is a much more stable bus.
Remember, that was all from memory, so my facts may be wrong.
Of course, if Apple makes available FireWire2, this becomes a non-issue anyway.
