A quick look on Amazon points to a £350/£400 price tag for a cut down laptop with no O/S. If you lose connectivity you presumably lose access to both data and applications, and at a price point above many laptops and pretty much all laptops. I have yet to see a decent online video editor or Flash alternative so you're also cutting down on what kinds of software you can get access to. For £100 I might have a punt. At 4 times that you can forget it!
