Wired.com has a Reuters piece about a new technology that reduces a television to just 50-millionths of an inch thick. You could roll one up and toss it in your bag.
From the story:
You’re effectively printing televisions,” CDT Chief Executive David Fyfe said. “They can be printed onto thin plastic almost like paper.” Roll-up televisions will allow viewers of the future to flip their sets out of sight like projector screens and will come with a price tag similar to regular TVs.
