There's a mountain of new devices being introduced at CES in Vegas this week and it looks like Fitbit is launching a new flexible wristband called Flex activity tracker. Gizmodo just got a few minutes with them to see it in action. Here's what they say about what they saw: "From the look of it, they've basically just reengineered the One, made it smaller, taken out the altimeter and shoved it into a wristband. Double tap the band and a stream of five tiny LEDs notify you of how many goals you've reached for the day. So if you've only hit two of your five goals, then only two LEDs will light up. The band itself seems a bit chintzy but is infinitely adjustable for any size wrist."
