honestly dude, final cut does not run very well on laptops.
unless you have a brand new macbook pro, or just a completely upgraded laptop than it will.
i have one of the black macbooks, i have 4 GB ram, faster processor and 500BG HD and it still "likes attention" if you will.
also, the resolution (especially color) doesn't really do your footage justice, thats why i ended up buying an external monitor to go along with it.
it's a great set of programs, but it's really built for desktops, or larger laptops (power and screen res).
