There has been a lot romanticized about editing on laptops recently. If you are a video journalist working in the field who needs to be able to edit together video quickly to send it off to broadcast then a laptop editing station is a good idea. For any other reason a desktop is better. No laptop is going to have the power and space that a desktop will. For a comparable price all desktop computers are of a higher caliber than a laptop, and though notebooks are developing quickly, desktops are doing so faster. You are not going to get the size of image or quality of sound needed to make aesthetic choices in your editing. You really need large monitors and a good computer stereo attachment to get the full feel for what you are actually working with. Since you need full focus, and the ability to plug in peripherals, there is no need to move around while you are editing. It is just an unnecessary piece of technology that will only hinder you while you are working.
