I’ve been working from an iPad as my main machine for the past couple of years now. Definitely doable (but as other have said, there’s _is_ pain when working local only).

I keep an AWS box spinning that runs docker and my dev env (vim as editor), then connect to this via Blink shell. This lets me port forward via SSH. If I need L2 I then use ZeroTier. My SSH key lives in my local Secure Enclave and then forwards via ssh-agent when needed on the external box (eg pushing commits). Background offloading is avoiding by enabling the geo lock, which also has the bonus of tearing down any SSH connections if the device leaves the lock area. Ends up as a pretty neat setup.

I honestly think there is a great opportunity for a Linux tablet plus pen input (high dpi; precision and low latency). People just don't know yet, that's what they want. FOSS would thrive there.
