A five-board flagship lineup running ZMK isn't a niche move; it's a market signal that an open-source firmware that lived in DIY-wireless territory for half a decade has crossed into mainstream-prebuilt anchor status. The vendor side has finally caught up with where the cohort already was.
Split doesn't automatically mean ergonomic, and ergonomic doesn't automatically mean split. Before spending money on either, a reader needs to know which of four separate design choices they're actually buying — and which one of them is solving their problem.
