Personally i wouldnt got a 17" screen unless its solely a desktop. As when i was looking for a laptop i was thinking about getting one. But when i seen how big it was it would have been a nightmare to cart around and i need mine to be quite mobile.
I got a New Packard beel as i had it cheap, lot of peeps dont rate them for somereason but i gotta say its mint for what i want with everything on it and i got it cheap too lol. Only complaint is battery life is crap! Maybe because its a P4? But personally if i was buying a new one it would have been a HP which i was going to go for until the PB came along cheap.
