Its an appealing idea. I thought of this last year and looked into it. It was a no-go then because of three factors: 1. The drive in a laptop was not fast enough (not processor speed, but access speed). 2. There is nowhere to put the video capture card. 3. The storage capacity required for video means you have to have additional AV drives to store data.(posted 9214 days ago)The technology exists by now - Sony has a portable editing system - but its not available in my price range. I have a Dell now -- which weighs almost 20 pounds stuffed full of cards and drives. Its a long way from the fantasy!
