Mobile phones still come with pretty limited operating systems though. I can't seriously shift my local home server [running on a beat up old 4GB ram intel computer, with various kinds of heavy duty services] to my 8GB mid-upper range android phone, even with turmux. Also, I can't turn my stock mobile into a good desktop like environment, given I have a big screen. I work with LLVM and Haskell, with Emacs or VSCode [lately], with some Blender3D mixed in. My phone was not built for this. It is a purely consumer device.
