The batch of phones going out in 19 days is not a finished product. It's expected to be loose fitting, not have endcaps on the switches, not have properly functioning power management and updates have to be done using a terminal. That's beta hardware, at best.

The next few iterations are improvements on the beta hardware but still not yet a finished product until Evergreen. That speculatively Q2 2020 but they've been off by miles with all the previous delivery dates so I won't hold my breath. Until that hardware comes out, which is what a consumer grade product should be, the only hardware delivered will be various levels of beta/release candidate.

By then, you might as well wait a few months for the hardware refresh. I appreciate the goal and the work done and if the hardware was polished and all the pain points were software, I'd be singing a different tune. Software can be fixed after the fact but poor fit and finish on hardware is forever. (And I've been Linux-as-a-desktop since the latter half of the 90s, so I can take a lot of pain. I'm all in on a Linux phone but I'll go buy a dumb phone while I wait for v2.)
