The International Consumer Electronics Show has been known to attract a celebrity or two, such as Justin Bieber last year. This year's event is no different.
Here's a recap of some of Wednesday's CES highlights.
The Las Vegas Convention Center played host to several recognizable names during CES. Musician will.i.am participated in The Next Generation of Innovators keynote, while former heavyweight champion Mike Tyson signed autographs at the SMS Audio booth.
Among some of the famous people the USA TODAY crew spotted:
-- Actor Danny DeVito spent time at the Panasonic booth to discuss technology and answer questions about his long career in television and movies. He says his favorite gadget is his iPhone, although he won't be leaning on personal assistant Siri any longer. "She's a ball-breaker," he says.
-- Samsung's CES keynote featured a special guest: the 42nd President of the United States. Former president Bill Clinton chatted about mobile technologyand how it can help combat social and economic issues. "The virtual world offers us an opportunity to have these sorts of conversations," says Clinton. He also reminisced about technology during his terms as commander-in-chief, including "five-pound" cell phones.
-- Jersey Shore star Nicole "Snooki" Polizzi used CES to tout her line of fashionable headphones, featuring rhinestones and leopard print. "I like bling-bling; I like bows; I like animal print; I like feathers," she tells USA TODAY's Mary Nahorniak. The headphones are designed by accessory maker iHip.
T-Mobile CEO on AT&T: 'The network is crap!'
Tell us how you really feel, John Legere, the head of T-Mobile who was quick to blast his rival in the wireless carrier business. And in light of recent customer surveys, he's not alone in his sentiment.
But as Ed Baig points out, Legere backed off those comments before claiming his carrier superior to AT&T.
The wireless company made several announcements at CES, including a multimillion-dollar tech deal with Major League Baseball that would improve communications between bullpen coaches.
T-Mobile also hints at becoming the last carrier to officially sell Apple's iPhone, although the carrier serves nearly 2 million "unlocked" smartphones.
Even radar detectors are getting help through crowdsourcing. Company Cobra unveiled its new line of radar detectors that relies on its users to update information on speed traps, red light cameras and other details.
The device is paired with an app for the iPhone, connecting via Bluetooth. One version of iRadar fits under the hood, which is great if you're driving in Washington D.C. or Virginia, where radar detectors are illegal.
NFL's Hasselbeck tackles concussions
Tennessee Titans Matt Hasselbeck is confronting one of the biggest issues facing the NFL: concussions. The player is at CES helping Reebok reveal their new Head Impact Indicator.
The black skullcap features sensors that detect dangerous hits to the head. A yellow or red light will appear if a hit goes beyond a preset threshold.
The Indicator will launch during the first half of 2013.
