Intel's cheap line -- there's a Pentium III based Celeron (though you're
unlikely to still find them in laptops) and a Pentium 4 based Celeron. In
both cases, they're basically the same core, with a smaller L2 cache.
Intel's mainstream desktop processor. Comes in three versions that might be
found in a laptop (regular desktop P4, P4-M -- the main laptop version, and
P4 Mobile.) If you're concerned about power consuption, I believe only the
P4-M has decent
Like the older regular PIII, but typically a very low voltage version.
Generally in lower clock ratings than last-generation desktop PIIIs... ie
AKA Pentium-M which is Intel's big mobile push lately. A newer design than
either PIII or P4, it's much faster at the same megahertz as a P4 for many
purposes, and much lower power consumption than P4s (I'm not sure how it
compares to the ultra-low-voltage versions of the P3)
If you're looking for a small, all in one unit with a flat panel screen,
that's a laptop/mobile.
It's unlikely for a desktop (separate boxes for the CPU, monitor, keyboard)
For Photoshop, it's probably more important to have a lot of memory than an
extremely fast processor -- I do work on 6 megabit images on a P4-M 1.8ghz
and it's more than fast enough, and I suspect even a PIII 750mhz that you
can get surplus would have been fast enough.
From what I've heard, a Pentium-M/Centrino processor is nearly as fast for
most work as a P4 running at twice the clock speed (ie, the 1.4ghz Pentium-M
will be comparable to a P4 2.6 or 2.8)... although the P-M/Centrino goes up
