Greenberg noted that one of themajor trends this year was that TV's are getting bigger and bigger. "Fifty inch TV's are so last year - but here's the problem, as the TVs get bigger - the resolution (picture quality) gets worse," he noted.

Greenberg pointed toLG as one vendor with a solution. He says it isthe first company to hit the market with an Ultra HD or "4K' TV. "Until now the best resolution you could get was 1080p, but the LG 84-inch ULTRA HD (http://www.LG.com) ($17,000) has 4 times the resolution of your 1080p flat screen.

So what about the problem that there isn'tany 4K content for the TV? "I would have to point out that today's movies are mastered in 4K and that build into this LG set is a "resolution upscaler" that automatically boosts lower resolution to something much closer to 4K, so you can enjoy it's benefits today," Greenberg explained.

He said anotherhuge trend here at CES involved tablets, and not just ordinary tablets, but ones that can replace a PC.

"With the speed and power of chips like the newest Intel Atom Processor, these new tablets like the Asus ME 400-C (http://www.intel.com/tablets) (starting at $499), can run the full Microsoft Office suite - including Excel and Power Point as well as Hulu and much more," he said. Greenberg said these tablets are lightweight, mega-powerful and have a much longer battery life.

Greenberg was also impressed bythe Wall of Apps that was on view at CES, as well as the App Lounge, andApp Showdown-where people pitch app ideas.

One new app that impressed him was a 3D coloring app for preschoolers. "It's called The Drip Drops: Color the World (http://www.thedripdrops.com), and it turns your iPad into a 3D coloring book with striking new patent pending 3D technology," he said.

The said the app uses six main characters, included Kellie, who encourages kids to use their fingers to color their world. "As they color different sections it triggers transitions from one scene to the next and "magical" special effects are unlocked," Greenberg explained. The Drip Drops: Color the World 3D Coloring App will debut in the App Store and Google Play in late January and other Drip Drops book apps are available now.

Another coolnew app he pointed to wasTRIPIT (http://www.tripit.com). "It's free and I can tell you that I use and depend on this app - it simply organizes your travel plans in one place. All you do is take your airline, hotel, car rental confirmation emails and just forward them to plans@tripit.com - that's it!" Greenberg said.

He explained theapp creates an itinerary in one place - including maps and directions."It will then sync your travel information with your calendar; and it puts your total information where you need it including your confirmation numbers on your smartphone," Greenberg said.

To try it out - just forward any travel confirmation email to plans@tripit.com.

Get to know other 4K options

During the CES keynote, electronics giant Panasonic followed in Sony footsteps by unveiling the second 4K OLED TV set at the show. No details on when consumers will get their hands on what will likely be a very expensive TV set.

So, what exactly is 4K? It stands for the 4,000 pixels of horizontal resolution on an HD display. That's 4 times the resolution of current HDTVs. The result is a product that is far sharper than what's currently available. But the higher resolution means a higher price. As we reported last year, initial 4K sets were selling for as much as $31,000. They make Samsung's Ultra HDTVs seem like a bargain.

But Panasonic wasn't done with the 4K revelations. It also unveiled a 4K tablet with a 20-inch screen running on the Windows 8 operating system.

Fitbit slims down

A new version of the activity tracker Fitbit is a comfortable wristband that tracks steps during the day, and even tracks your sleep.

As Jefferson Graham reports, the device sells for $99.99, and wirelessly syncs with Apple iOS and Google Android mobile devices through the Fitbit app.

The tracker launches this April.

New accessories for Wii U

Owners of the Nintendo Wii U video game console should finally have a solution to the fast-draining battery on the GamePad tablet controller.

Accessory maker Nyko revealed its line of supplements for the Wii U, including a PowerPak the company says triples the battery capacity of the GamePad. It launches this February.

Also available next month: a Pro Commander controller resembling Xbox 360 controllers and Charge Station that charges a Gamepad and two Wii remotes simultaneously.

Martian watch out of this world

Hands down, today's coolest device is the Martian wristwatch that responds to voice commands. As Jefferson Graham notes, Bluetooth technology allows users to answer phone calls and receive alerts on who's calling. The watch also reads back text messages.

The wristwatch works for both Apple iOS and Google Android devices. It was inspired partly by Apple personal assistant Siri.

"We realized it would be a cool idea to integrate that onto a voice command watch, as well, so it's an extension of the smartphone," says creator Jeffrey Hsieh. No word on the timing of the wristwatch's releases.
