I have a very similar spec Asus Eee PC that I use NetBSD with i3 on and it’s fine for like taking notes in vim or listening to music with strawberry. It can also run Haiku fine which I might switch to on it at some point because Haiku is fun. Anyway my best use idea is just use it to explore operating systems you’re curious about
This is why I love ostree distributions so much for my laptop. Not only can I safely update in class, I once switched distributions twice in one day of classes with only like 30s of total downtime, I just waited for the professor to go off on a tangent I didn’t need to take notes about so I could reboot.
