As a former K-12 sysadmin who maintained 10,000 chromebooks on my own I think that either of you doesn’t fully grasp how crucial these devices are. Web access is 99% of school device usage and for the few random CTE/STEM products or PASCO devices for science I’ll get a dedicated laptop locker with 10 laptops in it for checkout that run Windows with a base golden image and (preferably entune, but let’s be real) apps in SCCM Software Center so I can quickly wipe them when inevitably a student with more free time than myself either breaks it, deletes system32, or loads it full of porn or Counter Strike.
It’s for students. It’s cheap, it’s effective, it has minimal vulnerabilities that cannot be quickly resolved in 1 minute with a power wash. It has an easy admin interface for techs so I can have them manage smaller details, and it allows me to quickly get them repaired, or cheaply replace them.
