Not gonna bother setting up Nightly (switching browsers is a pain), but I hope this carries over to Samsung DeX's desktop mode, one of the updates a few months ago made the font way too large in DeX mode, making it almost unusable in that mode.
Yeah I basically run on my Samsung Tab S8 plus. Much lighter than a laptop and has everything I need. Also Samsung Dex is great if you've never used it. I also have a laptop with Arch Linux but I do most of my work on my tablet. For reference I'm a doctor and I use my personal devices for scholarly work. I use Google docs and refworks as my citation manager.
