In the PC world, firewire is more of a convenience than a necessity. 
Especially with USB 2.0.  My Gf's Dell has firewire and it collects dust
bunnys.

But still pretty fast <wink>.

The early P4's were.  The new ones (Hyperthreading) aren't.

And this is my point: with a 100MHz clock difference, the G4 is faster
(which implies a more efficient design), but if you extrapolate this out
to a 1GHz difference (or 1.8 GHz, which is the current gap) the G4 is
clearly going to be the loser.  If the G4 were available at 2.0GHz it
would be a contender, at 1GHz it isn't.  It's similar with the AMD chips
(which I use).  They're a bit more efficient than the Intel equivalent
but lag a bit in clock speed.

Ah.  Excellent.  Does it require another Apple to do the remote display
or special software on the client?

I'll check it out.  I've been curious about it.
