Well, the ratings are along the same scale, but how they translate into performance is different. I believe it's somewhere along the line of a Pentium 4 2.66GHz being in rough equality to a Pentium-M 1.6GHz, for general use. But when you get into heavier use and applications, the M falls off. Still not down to a 1:1 ratio with the P4s, but an M 1.6GHz is more in line a 2.2-2.4GHz chip. So the highest Pentium-M available on Dell now (1.8-2.0GHz, I think) might be comparable to some of the better P4 chips, there's still a falloff in performance, particularly as you get into heavier applications. But I'm well out of my comfort realm with this stuff, and I'm certain there are folks here who could share more meaningful and accurate perspective.
Take the Dell Inspiron XPS, which is their top-end "performance" machine geared towards gamers, and power-hungry applications. That's running with a P4 3.4GHz w/ HT, and offers (at a huge $ bump) an 'extreme edition' of the chip which has more cache. It's all back to power vs. mobility. Desktop replacements vs. travel books. No downside to either, just two different approaches. In terms of your decision making process, you really weren't going to go wrong either way.
I still feel that you'll be absolutely fine with either P4 or PM.
