Ask HN: Can't we just get a FOSS version of what Apple did?

Most of computer tasks can be done by a small suite of apps:

- edit text, view and edit photos, read pdf books, listen to music (all can be done by same application).

- edit and view video (could perhaps be done with same program also)

- organize files

- browse web in a container

- perhaps send messages over the net

Can't we get something that runs on ARM/x86 that does these basic things and has boot/lockscreen encryption? Why does everything have to be full linux? Something super simple and that boots fast? (I get that an OS has a lot more under the hood, but it could have less under the hood if it was just to carry out basic functions.)
