Where do you get this info?  USB 2.0 is actually rated higher (480Mb)
than firewire (400Mb).  The benchmarks I've seen vary, with each winning
by a slight margin on different tests and different devices, but I've
yet to see one that puts either of them 40% away from the other.

This is certainly a shortcoming, although most of the devices I've used
provide their own power anyway.

Not really seeing a problem with that.  But there may be applications
where this is a shortcoming.

If I want my USB HDD to sit in a different room than my PC, I'll start
questioning my sanity <wink>.

Agreed.

Ditto, which is why I don't think the presence, or lack of firewire/USB
is a real issue.  One or the other is fine.

Certainly.  I still haven't seen the G4 numbers though.

It matters because we are flaming over Apple vs Intel.  Every number
counts at this point <wink>.  Besides, you can be certain it's only a
matter of time (probably weeks or months) until we see 3GHz HT
processors in laptops.  My boss is running a Toshiba 2.53GHz laptop with
a 16" display ($2300).  I don't see the new P4's as being that big of a
jump.

And this is why using X11 would have been a benefit (at least to some of
us).
