One of my physics major friends uses a Chromebook (and a shitty Windows laptop he prefers not to deal with). I set up a DigitalOcean droplet for him to run Jupyter. One of the big problems is that it's not safe for him to share Jupyter notebooks by URL, since anyone to whom he discloses the web UI password gets remote code execution (exec and friends work).

A professionally maintained, sufficiently sandboxed Jupyter environment could be awesome for people who want to work on and share Jupyter notebooks, but not be responsible for servers.
