Other people have different work habits. I rarely reboot either, but I turn
my scanner off when I'm not using it. I don't feel like rebooting when I
need to use the scanner. If I want to unplug the scanner and bring it over
to another PC, I can do that too, all without shutting down or rebooting the
systems. So while the hot-plug ability of firewire offers you no advantage,
it certainly does to others.

It's still the biggest problem with SCSI. Eliminating the need for
termination is a big plus to millions of computer users.

Cable length is an issue for me. I need a 3 metre cable for my current
setup, which I can't do with SCSI. I'm sure I'm not the only one who
appreciates that flexibility.

Yes they will. It has been officially announced by Microsoft.

NT will disappear as older PC's are replaced. Some of my customers have
already moved to W2K, others will when they replace their PC (every two or
three years seems to be the average for corporate desktop users). I haven't
heard of any new NT installations for some time now.

One of the problems with the Pentium Pro was that it was really expensive to
manufacture, and that the design was being pushed to the limit. IIRC, it
could not handle any higher clock speeds. And unless a user was running NT,
the CPU didn't perform as well as the less expensive Pentiums of equivalent
clock speeds. The Pentium Pro cost two to three times an equivalent Pentium
CPU, but certainly didn't deliver an equivalent increase in performance.

Retooling not only enables a manufacture to introduce newer, faster
processors based on new technologies, they can also be built for a lower
cost.

A thousand for what the much slower Pentium Pros used to cost.

Yes, but an OS can easily be duplicated for pennies, where on the other hand
a CPU needs a five billion dollar fabrication plant. Mind you, at $30 for an
OS, that's far cheaper than what it would cost me to write my own. I'll
gladly pay the $30.

We were discussing current, not obsolete technology.

I do it fairly often. About two days for a complex setup is about the
average.

Not in the context of this discussion.

I suspect I know who my customers are much better than you do.

Let's keep focused on the topics at hand. We are discussing systems as they
relate to photography and scanning. How many photographers or press-press
houses do you know that are running software from 1968 and are still in
business?

I have to disagree again. Most professional computer users that I deal with
are likely to be running current technology and are the most frequent
upgraders.
