: Celeron @ 2.8 ghz
: Pentium 4 @3.3ghz

Two of the same family based on the desktop Pentium 4. The Celeron is
the "budget" version probably with a smaller cache meaning it will run
a little slower at the same clock speed. A 2.8GHZ P4 will run faster
than a 2.8GHZ Celeron. Obviously the 3.3GHZ runs even faster.

: Celeron M processor 380 @1,4 ggz
: Centrino Mobile technology Pentium M 725 @ 1.6 ghz

Both based on the Pentium M CPU, which was designed for low power to
promote longer battery life. As above, the Celeron version is cheaper
but is going to be slower and in this case, the Celeron M has fewer
power-saving features than the Pentium M. So a computer with Pentium
M should on average give longer battery life than one with Celeron M.

For performance, you have to keep in mind that Pentium M delivers
roughly the same performance (give or take a little) at about half the
clock frequency. So compare the 1.4GHZ Celeron M to the 2.8GHZ plain
Celeron. They would be about the same performance, give or take a
little.

I'd probably stay away from the Pentium 4 or Celeron and go with the
Pentium M. I worry about the newest desktop CPU chips being used in
laptops because of the heat the generate. Pentium M chips run much
cooler.

"Centrino" isn't a processor, it's a brand name. To have the "Centrino"
label the machine must use one of a specific set of Intel processors in
conjunction with one of a specific set of Intel chipsets, including an
Intel Wifi chip. If any of those parts are not on the list then you aren't
allowed to say that the machine is a "Centrino".
