Speed difference between Centrinos?

[voodoojc]

Anyone know just how big of a difference there if between the different Centrino processors? Worth the extra $100 to go from 1.6 to 1.8? Or $200+ from 1.8 to 2.0?

they scale pretty well, so it depends on how much you are willing to spend. ie 1.8 is about 10-12% faster.
however, MAKE SURE you get a Dothan core Pentium M. the Dothan has 2MB l2 cache, and also uses less power.
