Wearable technology too expensive to be popular

TOO PRICEY: Wearables need to come down in price for them to get popular

If wearable technology devices like smartwatches and Google Glass are to go mainstream, they need to come down in price

So said Astro Teller, head of Google's Google X research lab, in an interview with CNET.

"Every time you drop the price [of a wearable] by a factor of two, you roughly get a 10 times pick up of the number of people who will seriously consider buying it," Teller said.
