Why centrino is more expensive ?

[Saint]

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 Centrino is nearly identical to the Pentium-M.
The difference is that the Centrino has built in wireless lan capabilities.

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.
