I think Firewire or IEEE 1394 isn't about to go away because it is the
superior interface for highspeed transfers. The interface gets a boost
by being included with every single Mac, but, you've got to remember
that there are probably more IBM PC-clones out there with IEEE 1394
(and, whatever Sony calls their variant) than Macs ;-). Plus,
virtually all digital camcorders come with a Firewire/IEEE 1394
interface and only a handful with USB 2.0.
The advantage that USB 2.0 has is that it can do double-duty as a
el-cheapo, low-speed peripheral interface. But, that's also where its
weakness comes in -- those cheap peripherals and the necessity to
support them can cause USB 2.0 devices problems.
And, of course Firewire is now up to 800 Mbps. Not as fast as gigabit
ethernet, but, pretty good for external devices that are by-and-large
unable to saturate that much bandwidth.
It'll be interesting to see where the interfaces go in the next few
years. I would prefer Firewire because I find it a lot less
problematic than USB 2.0, but, that's the beauty of PCI cards ;-)
(and, if Apple ever dropped Firewire, I'm sure someone with a bit of
ingenuity would devise a USB 2.0 <> Firewire adapter)
