Most of the points you mentioned there were not immediately obvious to me from reading either of the pages we cited above, so I'll have to take your word that there is something relevant available even if I can't readily identify it. But to be frank, if it would cost that much just to get a useful Windows 10 licence, or even a handful of them, it's hardly going to be attractive compared to the other options anyway, even if there really are no other shenanigans.

I do appreciate your time writing these comments, but unfortunately what I'm seeing so far doesn't really look any more promising than anything I've come across in any previous discussions on this subject. If Microsoft ever decides to offer a simple licence at a reasonable price for a fully controlled edition of Windows 10, and if we haven't already got everything we need from the combination of six other platforms we currently use at my businesses anyway, maybe we'll take a look. For now, it seems their business model doesn't include having businesses like us as customers, and we're certainly not going to go out of our way to work around that and give them money anyway. After all, why on earth would we?
