We just got a few minutes with Fitbit's new Flex activity tracker. From the look of it, it's 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.
When asked why Fitibit was making a move to the wrist, I received a pretty bogus answer about not having to worry about the device being on the user's wrist. The fact of the matter is, the company is basically scared that it will lose ground to the likes of Jawbone and Nike. But we'll reserve judgment until the Flex ships this spring.
