Re: Enterprise Edition features is a capability called side-loading.
Far as I understand, side-loading is putting Windows 8 new style apps onto your companies' PC, not from the MS App Store, but from your company IT dept.
That doesn't mean that you can't install "legacy" pc software on Win8. But in the "dawn of time", Windows-wise, there were no Windows 8 app-store-style-apps. There were standard Windows programs and there still are.
Whether or not you like this approach is another question entirely. I don't find much to like about Win8 myself, which seems a low point, even for MS. Just got a laptop with it, for work, so gonna get acquainted :(
OK, I realize my own previous comment might have been a wee snarky, but neither was the article totally devoid of clarity so the OP was somewhat aggressive, IMHO.
And, yes, MS is greedy. All these different flavors of Windows, Home, Pro, Enterprise, compounded with OEM/upgrade/full flavors are annoying. As a SOHO I'd rather pay $X and get a CD that I can install one one computer at a time, but keep when I get a new machine.
