The P4m's aren't horrible, per say... just a bit deceiving. I had a 1.9 P4m, which meant 1.2GHz idle, 1.9GHz under load. I never really could figure out what was required to make the processor run under load, because it almost always was at 1.2GHz, even when working in Photoshop, Dreamweaver, and having a movie being encoded to DivX ... all at the same time.
But I would prefer an actual P4 over a P4m, if prices are the same/similar. I almost never ran my laptop without it being hooked up to an outlet, so battery power isn't so much a concern of mine.
