well that's true of all I/O standards and devices.
Yeah I use USB2.0 video capture device with my analog VCR and stuff, but 1394 when capturing from Tonys digital Camcorder. It's easier that way.
I'm not sure if anything except other Apples are compatible with 1394b. :dunno: but I suppose you could connect two macs together and copy things really fast across them :chuckles:
