Not necessarily! The Chromebook version starts at 1k, with a no-OS one 50 below that, both pre-assembled. Additionally, the higher build quality with the ease of part replacements would significantly reduce the load when it comes to repairs. The downsides of course are the high up-front cost, but this could be reduced by releasing in groups (by grade level, for example.) Also, an advantage with unrestricted devices like this is that it’s very easy to flash/install whatever you want, including whatever user permissions and applications are needed to ensure smooth operation (e.g. specific DNS/VPN configuration for content blocking or access to school materials.)

Either that, or I’m speaking out my ass. Still though, there’s a lower carbon footprint involved when you don’t need to huck the whole device in the trash once something breaks. That should at least be some kind of incentive…
