I find Google docs to be sufficient for most office, But I don't go too far into the weeds and Excel, It would probably be pretty easy have use cases where Google wouldn't cut it for you.

But I provision hardware for my job so I have windows boxes sitting around if I need them.
Yeah, seems like a reboot every 24 hours you're not unlocked would be extremely useful
