I must say, this was the most tame CES (and trip to Vegas in general) I've ever attended. I wouldn't say it was a bust, but it was a little "meh."
For example, TV hardware innovation feels like it has stalled. I know it really hasn't, but the major updates are not as physically obvious. For example, a few years ago was the year of 3D. Then there was 4k, curved screens, massive 115 inch displays, LED, OLED, UDH, etc.
This year felt like déjà vu. The booths felt nearly identical to last year. The TVs themselves were slightly thinner, slightly lighter, and a bit sharper. But nothing else terribly major.
Im actually "in the market" for a new livingroom TV in the 60" + neighborhood. The curved TV's have somewhat of a novelty. However the curve actually means they pull away from the wall on the sides.
If you are looking for a truly flush mount (like I am), curved TV's defeat the purpose.
One pretty cool thing tucked in the corner of one booth were these transparent screens (below). They are in the prototype phase, and there aren't an practical applications just yet.
One day, windows could be both a TV and...well...a window. Definite commercial applications here. Think storefront windows, etc. But it would be pretty cool to have one of these at home just because.
