I would, which is why I wear a Garmin now despite having backed two Pebble Kickstarters. AFAIK, a FitBit does everything the original Pebble did, which was mainly put notifications on your wrist. I know my Garmin does everything that the original Pebble did (mainly notifications), and I can use it when I go running without having to bring my phone.

So, yeah, in comparison the original Pebble, FitBit is a smartwatch as defined by the smartwatch market in its current state. That doesn't mean that I don't think it's early days, just as you with your laptop comparison.
