CNET CES roundup: 4K tablets and TVs, ZTE Grand S

News and previews are pouring in from CES 2013, but dominating the chatter is the advancement of 4K screen tech.

CES is in full swing, and while press day has been and gone, the news and announcements are still pouring in. Hopefully you're not already all geeked-out for the week, because the CNET team have been busy previewing some very cool kit just for you, you lucky thing.

Panasonic quietly stole the show yesterday, with a 4K 20-inch Windows 8 tablet, which has a staggeringly high 3,840x2,560-pixel resolution and runs on an Intel Core i5 processor. CNET UK editor Jason Jenkins saw it on the show floor being used as a tool for photographers and artists and was genuinely impressed. It's also produced a concept 56-inch 4K OLED TV, similar to Sony's effort, and really quite spectacular.

Smart phones are few and far between at CES, which isn't surprising considering they get their very own dedicated trade show, MWC, barely a month later. That hasn't stopped several less well-known phone manufacturers parading their mobiles though, perhaps taking advantage of some free space in the spotlight.

ZTE's Grand S is a 5-inch phone with Jelly Bean and a 13-megapixel camera on board. It's been dubbed ZTE's "most chic handset" by CNET's Lynn La, who went hands-on with the device.

Other phones keen to see their names in glitzy Vegas lights are the first dual-core Intel phone, the Lenovo K900, a Windows Phone from Huawei and the YotaPhone, which rather intriguingly marries an E-Ink screen with Android.

In other news, our very own Luke Westaway showed off his best Queen's English when he spoke to Samsung about its curved OLED telly concept, at which can you take a peek in the video below.

Innovation is a word bandied about all the time at tech shows, but serious props to the folks who invented Spike, a case that transforms your iPhone's disconcertingly smooth capacitive touchscreen into a plastic BlackBerry-esque keyboard. Wait, what?

Don't forget to check out the dedicated CNET CES page, which is home to all the news, videos and previews from the show. CNET editors from around the globe have been going hands-on with exciting products such as the Sony Xperia Z, the Razer Edge gaming tablet and the Philips AEA7100 Starmaker karaoke machine (which you can also see in the video below) -- don't miss it.

There's still plenty of good stuff coming too -- the nominees for this year's Best of CES Awards will be announced later today, with all the winning products crowned in a ceremony tomorrow.

And let's not forget the CNET UK podcast, which will be recorded in Vegas this week, as Jason and Luke are joined by a very special mystery guest. It'll no doubt be a corker, possibly even on a par with Qualcomm's keynote speech in terms of entertainment value, and you can watch it live at 10pm UK time.
