Here isn't USA, I repaired my VCR and I hope it will work another 5 
years, and I repaired my TV and I hope it will work OK ten years 
more.

Sorry but I couldn't resist.

Just to add some clarification (doesn't invalidate, agree or 
disagree): Firewire (IEEE 1394 if I remmember well) isn't the 
successor of USB. But will trash USB for sure. The standard was 
started 10 years ago by the Apple people to make what USB does today 
(remmember Macs have serial mouse and keyboard  in the same BUS, 
Firewire started as a replacement for it). 400 Mb/s is one of the 
starting rates, 800 Mb/s and 1.2Gb/s are specified and under test.
I think we will see USB and Firewire both at the same time because 
USB was very delayed, now WinCrap 98 supports both.
