The '07 2.4GHz is actually faster in some tasks than the new '08 Penryn 2.4GHz due to more L2 cache .
I still use my 2.2GHz Santa Rosa and I will use it for atleast one more generation I guess, since I really can't feel the difference between mine and the new ones.
Here for the full test between the '07 2.4 vs '08 2.4 and 2.6
oh that explains a lot.... but still, im skeptical as to why would a computer company put a processor that may be backward than its predecessor in some cases...
but thanks for sharing the info, that def. helped me set my mind.
