I would recommend you avoid the new P4 notebooks; I did a home setup for a friend at work who just purchases one of the new 16.1" VAIO P4s. Boy, it sure is a POS. I was amazed at how many times the computer failed to shutdown properly. It also ran EXTREMELY slow at times. Just loading windows took a good 4-5 mintues minimum. Not only that, the new P4 notebooks get barely any battery life. The laptop went from full to dead in less than 2 hours. Also to note, the laptop was huge, screen seemed too big, was really heavy for a laptop, and you should have seen the charger; the damn thing was almost as big as a normal notebook (exagerating), but it is definately at least 2x as big as a normal notebook charger. I think the P4M is a terrible part, and has been released to market way too early. Just my $0.02
