Centrino is *not* a "processor" - it is a package that includes the
Pentium M CPU (and a chipset and an internal wireless card). If you
get a Centrino-based laptop, it has a Pentium M in there. You can
also get a Pentium M-based laptop that is not "Centrino" with someone
else's wireless card, perhaps, but now that Intel has improved the
wireless to be 802.11g, this will be less and less common.

Pentium M is not merely a "mobile Pentium" (that would be the Pentium
4-M) - Pentium M was designed separately as a power-saving CPU. The
big benefits are longer batter life, lighter laptop design, and a
cooler machine that hopefully won't burn your lap because of excessive
heat. Yes, there is a big difference. As of now a Centrino-based
laptop costs more than a "regular" Pentium or Celeron-based laptop.

"Centrino" is a full specification intel-provided Pentium-M processor +
Intel 802.11b wireless + Intel power saving chipset.

A manufacturer who choses to not implement the entire "Centrino" suite,
i.e. one who uses a wireless chipset from another manuf. along with the
Pentium-M, will not be able to use the "Centrino" label but may still be
providing a system equivalent to, maybe better, maybe worse, than a
"Centrino" system.

lycka till!
