The notebooks of centrino is more expensive than that of P4-M , why?
Centrino clock speed is lower than P4-M, such as 1.3GHz vs 2.2GHz.

How about the performance? What is the advantages of centrino conpared to P4 ?[?]

I think centrino uses less power so the battery lasts longer. I also think low power CPU's are a developing technology so they need more money to keep funding the R&D.

The difference is that the Centrino has built in wireless lan capabilities.
Actually, the Centrino MOTHERBOARD has integrated wireless lan. But the centrino PROCESSOR is actually built from the ground up different from the P4-M. Its also known as the Pentium-M.

The reason it is offered at lower clock speeds but is more expensive than the P4-M is that it is much more efficient than a P4-M. I'm not sure exactly how much, but a P-M at 1.3 ghz is probably equivalent to a P4-M at 1.8ghz or so.
