The entertainment is sweet on the HP Pavilion dv4000, a great consumer laptop that serves up DVD movies and CD music without requiring you to boot up.

It's hard to agree with this format as there is little benefit for a lot of work and considerably more noise. It's not that it hasn't been well engineered or that it doesn't produce good results, it's just that it doesn't seem worth it. For the same price you can get an equal performer with less of a heating issue and less bulk. As a desktop replacement it's fine, but as a notebook we're not impressed.
