USB 2.0 is actually quite expensive to implement. The chipset is roughly
3 times the cost of a standard USB 1.x one.

So surely the same will be true of USB 2.0? Why do you expect the
adoption of USB 2.0 to be quicker that that of Firewire?

No, I didn't say that at all. USB 2.0 is almost exactly the same as
Firewire.

It is reinventing wheel when Firewire does almost the same job. The
example you gave of SCSI and IDE is an interesting one as both standards
do the same job very, very difrently. USB 2.0 and Firewire are so close
as to be pointless.

We could always fart in each other's faces ... that's a favourite of
mine.
