Netbooks are light enough to throw in a small bag and carry with you wherever you go. Smartphones are even smaller and lighter, and fit in your pocket. But there are compromises that come with these portable devices. It’s hard to fit a large screen or keyboard on a device that’s designed primarily for portability.

But that could change in the future. There’s been a lot of research into flexible displays over the past few years, and Sony has put out an awesome video of a Sony rollable display that can show full motion video as it’s being rolled and unrolled.

Sony’s display is an OLED screen that measures just about 4 inches and has a 432 x 240 pixel resolution.

The technology isn’t quite ready for prime time yet — and even when it does hit the streets, I don’t expect it to be cheap. But we’re one step closer to a day when you can sit yourself down in front of a computer, video game console, TV, or other device with a 15 or 20 inch display and then roll it up and stick it in your pocket when it’s time to go.  Or maybe we’ll just see funky wristwatches.
