It's meant to be your real phone. They're just afraid to advertise it that way. It's truly bizarre to choose this advertising theme, because it almost causes confusion, since there have been phones in the past which truly are companion phones, totally tethered to your primary phone for their connection but besides that little (huge) dependency, were meant to be like...minimalist, distraction-free devices. Advertising the Communicator as a "second phone" absolutely summons up that same idea, in my head at least. If they did some of the app curation or de-googling of, for comparison, the SLEKE phone project, then they could full-throatedly sell this as a minimalist dream. But they don't want to lock out any kind of customer, and so they're struggling to make a case for who the customer even is supposed to be here. So they just call it a "second phone" and let you decide for yourself whether it could be a primary or a second or nothing at all. I'd buy it in a heartbeat if I didn't have a bunch of frugal reasons not to, and if they hadn't also announced an accessory so seemingly excellent that it encourages me not to give up my current phone for many years to come.
