The P-M is a more efficient CPU - a 1.8 GHz P-M will run with a 2.8 GHz P4.
Cons of the P-M - more expensive.
Cons of the mobile P4 - much higher power consumption, shorter battery life, more heat, likely shorter component lifetime (many Mobile P4 systems - not just Dells - have had major overheating issues, which shortens the life of everything in the system).
Pros of the P4: CPU speeds of up to 3.8GHz available, the 600 series has a 2MB Level 2 cache, Windows XP Pro x64 is soon to be released and the P4 CPU is available in 64-bit versions right now to run it and the new 64-bit games and applications soon to follow. Battery life is shorter than with a throttled down PM but a PM cannot hang with the raw numbers crunching power of a high speed P4.
Bottom line is if you need to run off batteries for hours and hours you might consider getting something with the PM CPU. I personally view a battery as something that can be used to backup files in the event of a power failure. A system will run slower off battery power than A/C anyway.
Read all about the line of Intel CPUs at www.intel.com and the upcoming release of Win XP Pro x64 at www.microsoft.com and decide for yourself.
Having purchased a p4 3.4ghz laptop I wish I had waited a while for the higher speed pent mobile, the newer 2.4 ghz mobile is supposed to be comparible for gaming and general use than the 3.4ghz.
