Intel Will Trim Pentium 4 Power Consumption to 65W
 

The world’s largest maker of x86 processors Intel Corp. reportedly plans to introduce a new version of its 65nm Intel Pentium 4 processors code-named Cedar Mill that will have power consumption inline with the company’s next-generation desktop chips known as Conroe. Low power consumption means that mainboards and cooling systems do not have to be very advanced, thus, will get less expensive.

Intel is finally getting there were they should be 2 years ago.
This cpu will be a good overclocker on air I guess.
