electronics show at the beginning of january, we saw this big trend in wearable technology. the push for wearable technology or what makes it really attractive is all this health care stuff we can get. we can know how many steps you took and track your heart rate monitor. it's a tiny little thing. it has a nice, high resolution screen, a heart rate monitor on the back. i just took my heart rate. you can fell i have had too many cups of coffee this morning. it was a little elevated. that information is then going to sink up with the phone so it can keep track of my heart rate, i guess, throughout the day. or if you are really into physical fitness, a whole lot of apps that take advantage of this information. >> how much would this cost us if we would like to buy one of these phones.
