Apple touts iOS 13 (iPadOS 13) as having a desktop-class browser but I watched the presentation from their developer conference about it. Really it’s the same browser but they falsify the user-agent and use some proprietary heuristics to decide how things like CSS :hover, :focus, etc. pseudo classes are handled. Thing is, using Firefox in tablet mode on Windows works just as well, if not better, than Safari on iOS. I mean there’s always going to be web sites that suck for touch interfaces (Lenovo’s is actually a great example) but it more or less works flawlessly (and I get a web inspector, and add-ons, a console, etc.).
(I’ve also been trying out Microsoft’s new Edge browser, based on Chromium. I’m on the beta channel for that and it works pretty well, too. Of course it does, it’s basically Chrome with the Google crap swapped out for Microsoft crap.)
