it's been awesome ... i've been using this setup for 7+ years. Obviously with other phones (former pixel 5) but the passport form factor of the pixel fold works great for one handed use and I use it folded most of the time. Unfolded is just icing on the cake.
I build webapps so there's no difference using my phone or a laptop save for app switching/multi-window speed. As for typing speed, sure it's a bit slower but it helps I program in clojure(script) so the concise and terse syntax helps.
Also, when I need to dive into developer console I use KiwiBrowser which is slower to get around compared to desktop chrome but it gets the job done.
I've been meaning to share the minimally modified APKs I use and write a blog posts.
