(CBS News) When people say, "What happens in Vegas, stays in Vegas," they're not talking about the Consumer Electronics Show.
The technology-related trade show, held each January in the Las Vegas Convention Center, is not open to the public but CNET editor-at-large, Brian Cooley has the inside scoop on the latest high-tech products that may one day be in your home or office.
Cooley called the new 4K televisions one of the most interesting examples of product evolution he's seen at the show.
"Basically, it's taking the best HD picture we have and doubling the amount of resolution, the amount of fineness and clarity you have," he said. "And it's part of how the industry is trying to reinvigorate TV sales."
Sales of flat panel televisions were down for the first time in 2012, and higher-resolution screens are one way to get them back up again. But since the technology behind 4K is entirely new, don't expect the prices to be low anytime soon.
What do you get when you combine a phone and a tablet? A phablet, of course.
Though smartphones are not a huge trend at CES -- there are other shows for them -- 2013 is seeing the rise of the phablet. Depending on your point of view, it's either a really big phone or a mini-tablet.
"The biggest phone I've seen yet -- a 6.1-inch smartphone," Cooley said. "That's a big phone. That came out from a company... called Huewai, that's trying to make a name, so they're doing something different."
Moving beyond the mouse, keyboards and touchscreens
If a computer mouse, keyboards and even touchscreens remind you of your father's Buick, you might be ready for the Next Interface: You.
Cooley said there are more and more products being introduced that use the body to control the movement on your device or screen. Some allow you to wave your hands, while others track your eye movements. And one even tracks your brain waves.
"The Muse headband... This is reading my brain waves and can control an interface on a product wirelessly that it's connected to," he said.
