Surface also uses these magnetic connectors btw. So either there is a patent sharing agreement, so they have somehow circumvented it.

Apple and microsoft have a permanent patent deal since the 90's. They can use each other's patents for free as long as they don't make direct competitors. Hence why this is a fitness band and not a smartwatch ;)

Microsoft have a patent on power-and-data connectors, which have shown up on devices before (I think ms kin phone had one)
