What is a Pentium M chip?

I'm considering buying a laptop for my next PC (the thought of being able to surf wirelessly while plopped in front of my TV, and 18 months no interest financing at Best Buy this week has me hooked), and when I was looking at them, I noticed some had something called a Pentium M chip whcih seemed to have lower processing speeds than those with regular Pentiums...what's the difference? I'm guessing the M is for Mobile...correct?

It's part of Intel's Centrino technology/marketing.

My understanding is that Intel makes three Pentium mobile chips: Pentium III-M, Pentium 4-M and their newest, the plain Pentium M.

The Pentium M is part of the Centrino family which also includes a chipset and a Wi-Fi chip, both made by Intel of course. Laptops that use all 3 chips get a Centrino sticker. Some manufacturers might use a different chipset or a different Wi-Fi chip, so their laptops are no longer Centrino but just get a Pentium M label. I don't know how big a difference there is between the Intel chipset or Wi-Fi chips and those made by other companies.

I have used Centrinos made by IBM and Dell, and I have to say they are great systems. Some of the advantages are speed (most reviews say a 1.6 GHz Centrino will run about as fast as a 2.2 GHz Pentium 4-M) and long battery life. Since it also runs cooler, Centrino laptops are also lighter and thinner, typically 1 or 1-1/4" thick as opposed to the usual 1-1/2 or 1-3/4" thick Pentium 4-M laptops.

More info here, although these articles are fairly old:

The Intel stuff is supposedly made to have a very low power consumption. If, for example, you get Dell's combo B/G card instead of Intel's B card, you won't be guaranteed the good power consumption of a pure Centrino setup.
