A man recieves an explanation on the Fit

A man recieves an explanation on the Fitbit Aria Wi-Fi scale, which can tap into a home wireless network to upload information on one's health each time the scale is stepped on, displayed on the opening day of the International Consumer Electronics Show on January 10, 2012 in Las Vegas, Nevada. The show kicked off with a dazzling array of high-tech gadgetry including ultra-thin laptops, snazzy smartphones, iPad rivals and flat-screen and 3D TVs with a record 3,100 companies from around the world displaying their goods over a space equivalent to more than 35 football fields in the cavernous Las Vegas Convention Center for the four-day event.
