The easily replacable parts feature sounds like it'd work great in a university context. The uni's service desk could stock up on replacement parts and fix the phones right there instead of having to send it in for repairs.

If e.g. someone's mainboard breaks, they can just give them a new phone and take in the old one, and then use the remaining parts to repair other employees' phones with working mainboards.

Same as any other major employer, surely? At least, you’re describing how it works at my previous employer (large private enterprise).
