I have spent a fair amount of time using just an iPad Pro while travelling. To be honest, I have been finding a much cheaper Lenovo Chromebook to be better in some regards: slightly lighter, and Linux container support makes it possible to do some things locally. For deep learning, I like Colab, and any device is OK for that.
Thus, yes, indeed Haskell and SBCL or anything works exceptionally well - even operating systems such as NixOS https://github.com/gitpod-io/template-nixos

I've been disappointed with my Lenovo Chromebook. It's more unstable than Windows 98 for anyone that yearns for the good old days. Several times a day I would be typing away and it would restart without warning. The previous sentence is past tense because I gave up and now use only the browser.
ex. i was on vacation visiting my twin for a week and left my daily driver at home to wind down -> got a gh notification about a bug and released a PR on my sister's computer within a couple hours.
