Pentium M CPU which is 4 or 5 years ago. It is a shame for Acer to put a such configured laptop to market, why do you need a low power CPU on a 15.6" laptop, you will carry it on your trip?
I assume 15.6 is for desktop replacement, powerful is most important, not power saver. SO obviously, PP10002's choice is better. AMD's CPU is good enough if you want a low end laptop.
