We have four Dell systems, three laptops and one desktop and they're
generally one to five years old and all work fine. Most of Dell's
business is with companies and they provide their best service to
company clients which is why I've ordered from their Small Business
department instead of their Home section and I've been pretty happy
with their service. I haven't really used it that much but, outside
of a few phone calls with some folks in India, it was good.
Dealing with large companies can be a headache if you're not
comfortable with being very annoying.

In Windows XP, you can set the priority of programs using the Task
Manager. If you know that you'll be running something that could
saturate the CPU, just set the priority to below normal. Or keep
the Task Manager running and set it to high priority so that you
can modify processes that are saturating the CPU.
Same deal with Unix/Linux/OSX. I don't recall the commands for setting
process priorities on Unix as I have a dual-processor Linux box at
work and the processors usually have lots of spare cycles.
A 2.0 Ghz Pentium 4 is a low-end machine these days. I don't know if
you can still get machines this slow. My current laptop is a Athlon
64 running at a 3.2 Ghz Pentium 4 equivalent and my CPU is on the
low end of the scale. The upper end is 4.0 to 4.2 Ghz equivalent.

My guess is that it depends on the software that you're running.
I've only had a machine since Monday but it appears to me that
great performance is directly related to optimization work. The
G4/G5 have Altivec parallel instructions but your program has
to be programmed to use the parallel instructions.

Some Dell notebooks can take two batteries and some can only take
one. One of my older Dells can get 7 hours on two batteries.
Pentium Ms generally have the best performance to battery life.
