Mhm, they seemed have swapped the master/slave relationship between the smartwatch and the smartphone that most recent systems use. Now the watch unit has the data and the connectivity interfaces, instead of the other way around. Looks promising, if battery life of 'the Hub' is somewhat decent.

Well, from the product page, the pocket screen actually has more battery capacity than the armband. In fact, the screen can be used as a on-the-go charging station for the armband.

Personally, I don't know how I feel about this. Their battery benchmarks are assuming you're going to use the pocket screen to charge the hub, but I don't necessarily want to be tethered to this pocket screen either.
