If you are into video editing then you might want to consider getting a machine that is on your preferred software makers approved list(s). For instance Avid have tested out a number of laptops and desktops from Dell, Compaq and HP and have a page on their website saying what features they expect each laptop to be able to handle. Eg with or without Mojo, HD or SD etc. I also understand that if you put their software on a non approved machine then there is the possibility that they may turn round and say 'sorry can't give you support as our software is not on an approved machine'. (I could be wrong about that but you never know.) There is also a lag between a new machine being launched and it being tested and approved.
