But according to a survey from the magazine Fortune, many Americans have a simpler wish: better batteries.

According to Fortune's survey of more than 1,000 adults, conducted in collaboration with Survey Monkey, "only 2 percent said they were extremely or very likely to buy Internet-connected glasses, such as Google Glass, in 2015."

And 4K television didn't do much better. Seventy-five percent of respondents said they had never heard of it.

Meanwhile, consumers indicated that the new smartphone feature they were most excited about — picked by 33 percent of respondents — was "improved battery life."

Alan S. Murray, editor of Fortune, says he was struck by the survey results while walking around the halls of CES.

"You have to realize, this is like 2 1/2 million square feet of display space with all these drones flying around and these mammoth curved televisions with 4k ultra-high definition," Murray tells NPR's Arun Rath.

Even in this high-tech wonderland, he says, there were "an awful lot of people running around trying to findpower strips so they could plug in their smartphones that had run out of battery juice."
