*facepalm* GSO, I believe it's best that you read the OP's purpose / read replies before you even jump straight in with your first thoughts. prophetik is in to build other people's PCs, not do recommendations for pre-packaged PCs you want to get.
To answer your question though, if you're thinking of doing video editing on a laptop, I highly recommend that you find one with a stronger processor (2GHz multi-core at the minimum is my suggestion) and at least 4GB of RAM - main reasoning being that CSS 5.5, Vegas 10 and Final Cut Pro typically recommend these before you consider using them. If you have more money to burn, consider going towards a quad-core processor and doubling the minimum stated RAM for more intensive editing. Either way, they'll still degrade faster than a desktop PC due to their build.
