M series are good. Depending on cache and clock it'll be similar in speed to Core Duo on single-threaded apps. But, the same money buys a faster clocked single-core processor. If you only run one thing at a time M might give you more bang/$. Same situation as Core Duo vs. Turion. The choice would come down to actual laptop configuration, price and how you plan to use it.
Really, there's so much more to a laptop than the specific processor. All my generalities assume the rest is equal. That's almost never the case. The best way to narrow your requirements is to try one. Buy your favorite and see if your priorities match reality. Not easy to do if you're ordering online but sometimes that makes buying local with liberal return policies a better route.

The propaganda that inundates them is effective when unchallenged, but much of it goes only skin deep. If they can be brought to raise questions and apply their decent instincts and basic intelligence, many people quickly escape the confines of the doctrinal system and are willing to do something to help others who are really suffering and oppressed." -Manufacturing Consent: Noam Chomsky and the Media, p. 195
