My wife works at a “Chromebox workplace”. I’d say they are mostly meant for organizations who naturally are not IT-heavy (schools, healthcare) who are looking for cheap computers that are easily maintained (as everything happens in the browser) and that work for employees who don’t like or lack the expertise to babysit a computer.
These are likely the same people that would never even think about upgrading a charger. Until now they just borrowed their coworkers $3 charger and now they can just put their phone on top of their computer.
Target market appears to be the high-density enterprise.
But obviously I’m not in the target audience, because that feature has received positive press.
