first of all, if you intend to use a notebook for graphic designing, go for a Mac.
if you want to stay with a PC, go with P4 rather than Centrino. Centrino just makes notebooks more mobile (longer battery life, Wi-Fi, slimmer designs, etc). however, the rating for P4 and Centrino processing speeds are different because the processors are (essentially) 2 different processors (apples & oranges)... a Centrino processor is NOT a variation of a P4 processor. i read somewhere on CNET that a 1.4GHz Centrino processor is as fast as a 2.5GHz P4... hope this helps!
I'm shopping for a new laptop that I use mainly as a desktop since I don't travel much with it. I do lots of processor and memory-intensive high-resolution graphics but need the portability of a laptop. I'm reading so much about the Pentium M (looking at Dell 8600) and Intel M P-4 (as in dell 5160) but I can't seem make sense of it. Bottom line is I'm looking for the best processor. Power is important; batter life is NOT as important. What am I best with as far as these processors...any suggestions?
