Maybe not "barely usable," but it certainly makes it more like a "terminal" of the old days or a "thin client" than anything, especially considering how bloated macOS is. This machine would fly however with Linux and a lightweight DE.

For the average user (office and student) this is all they need, access to office apps, ChatGPT and their google cloud and that's enough. They don't need it to "fly" through coding tasks and games that's not what it's for.
