I bought an HP laptop a month ago with the T8300 processor (2.4ghz). Because of some dvd problems, im thinking of sending it back since im still within 21 days of use.

I just noticed HP now has a new model with Centrino 2 technology, namely the P8600 (2.4ghz) processor. Should i go for that one; will it be a big improvement over what i've got? Or should i stick with getting the old model?
