We started using computers with keyboards in class in grade 2-3.
Another school uses iPads with keyboards for the same purpose, so I'm not sure where the school market is for these. Maybe only older kids, but a lot of edu-tech is expecting some kind of touch/pen input.
I just wish the Mac had 16GB of RAM but my tiny Lenovo has 8 and it’s been working OK so far - I haven’t even set up a proper swap partition and it’s running on zram.
