The bottom line is Intel is putting its efforts into updating the Pentium M Centrino technology (3 times since its inception) while the Pentium 4M, at least for notebooks, is pretty much at the end of the line as the 4mhz Pentium 4 project was pulled already last year.

The Athlon 64 Turion is coming and Intel has its own 64bit chips coming but the Pentium M Centrino (Sonoma) is still the best pure notebook cpu out there right now and it is not standing still (or burning up like the Pentium 4M).

Only hyperthreading and an 17" gaming desktop replacement system really still belong on the Pentium 4M going forward on a desktop (but the Pentium 4 is still the king of desktops with the Athlon 64 making inroads)
