Not trying to derail the topic or anything, but this honestly looks too much like Sony's Smartband Talk, both in terms of looks and functionality, except MS Band has a GPS and a normal screen (with a better interface), whereas Sony's Smartband is waterproof and it has an e-ink screen. Oh and battery wise, the Smartband should last 3-4 days, compared to the Band's (probably less than) 2 days.
