In today’s world, nothing escapes the fact that we are moving in a direction where quantifying and recording stuff obsessively is sort of the norm. We use Foursquare to check into places, we annoyingly take photos of our meals with Instagram, and we share our thoughts on Twitter. So would it be much of a surprise if we also like to track the number of steps they take, or how much we sleep? Today, we’ll put the Fitbit Flex and the Jawbone UP against each other, and decide whether it’s the newcomer or veteran who takes home the gold. We’ll also be offering both devices, so enjoy the review then remember to join the contest.
