Just a side note if anyone is interested. (I hope it doesn't detract from the forum).
I find working with an android 7" tablet using a Bluetooth mouse and keyboard and running Termux, very satisfying.
I can run Jupyter offline, use vim, taskwarrior, nodejs, and much more.
The only reason I say this is because I was chasing the idea of using iOS for a while. I have the computable app which actually has Pandas installed and that was nice but it had been discontinued and is missing some key functionality.
Also I think Pythonista is awesome but I missed using a mouse.
