I run Poser 4, 5, and 6 on my laptop. CPU speed, hard drive speed (especially on a laptop), and memory are the things to consider for laptop use. I have a AMD 64 3ghz with 128mb vid card and 2 gig of ram. Poser is a dream. I would stay away from Celeron laptops, while they are great for general use when you start pumpin graphics stuff they lag a bit. As others have said, RAM as much as you can afford. On a laptop ram gets expensive fast, but get as much as you can get. I bought mine at Xtremenotebooks. They offer more ram in base models as well as a dvd burner included. bit more than Dell prices, but only a little bit and ya get more bang for $300-$400 more.
