Consumer Electronics Show (CES) 2013

CES is a technology geek's playground.

Interesting, but not ready for prime time (in our opinion), was the Displair (http://www.pcworld.com/article/2024879/displair-gives-you-a-touchscreen-out-of-thin-air.html)—a touchscreen that floats in the air.  A "screen" of microscopic drops of water are shot upward from a fairly large tabletop unit, and a projector can display onto this water-vapor screen.  Most intriguing is way that the projected image responds to touch.  At $10,000, this seems more like a prototype and needs work.

There was a lot of talk about moving PC gaming from your desktop to your living room.  What can be better than high-definition video on a life-size screen with life-like surround sound?  Agreed: nothing.

Of course, OLED and Ultra HD were probably the most talked about.  Not yet affordable for the masses, they're on their way.  (http://www.pcworld.com/article/2024911/oled-and-4k-at-ces-2013-the-fantasy-and-the-reality-video-.html)
