Yeah a lot of retro games on GOG were fixed up with patches and stuff like that (often by GOG themselves) and sometimes regardless of any fixes applied, there are version disparities between the two platforms where usually the Steam versions is a slightly older release of an old no longer updated game compared to the GOG version though I’ve seen it happen the other way around, too.

You can already buy those. They seem to commonly be referred to in online stores as ‘pocket wifi’. Just stick a sim card in them and you can manage their settings through any connected device with a web browser.
