Pentium M and Mobile Pentium 4 are two completely different processors. Pentium M is based on Pentium III core, and therefore way faster at same frequency than Pentium 4, while drawing less power (longer battery life, runs cooler). Centrino is a version of Pentium M. Currently fastest Pentium M processors run at 2.26GHz (which is actually faster than that Pentium 4 at 2.8 GHz you have).
