...what was the business case for writing a library set for some very limited conditions?
I mean, yeah, I guess it would be kind of cool to run Windows x86 binaries on certain models of smartphone and all, but honestly, under what conditions did they think this would be useful (beyond the obvious 'gee whiz' factor)?
Mind, I'm not normally one to go reaching for business justifications and such, but I can't shake the feeling that they did this to, well, stay relevant. These days, if there's an application that I really need that only runs on Windows, I either find a workaround, or fire up a VM (viz. VirtualBox) and do whatever it is I needed to do with that application.
There was once a time where something like this was IMHO desperately needed (I'm talking long ago, back when Win4Lin was a thing), but nowadays? I just don't see it...
