And yes, i think there will eventually be Modern interface versions of all those programs you listed only to be purchased via the MS store. Who's to say they can't be written in the Modern interface? MS will get a cut. They also keep track of what's installed on one's computer. Ever see the "My Apps" in the Store? I recently performed an install from RP to Enterprise. All my apps nicely listed in the Store ready for me to click the button for me to install again. So they keep track on a server. I think MS finally woke up to the fact that software companies have been sponging profits off their OSs since inception, especially AVs. That's why Defender was written kernel deep just to name one tactic.
I think 3rd parties are very interested in this concept for it will cut way down on piracy. Do you know how many illegal copies of AutoCad (just to name one of many) I've seen on PCs through the years? -> Many. How many $millions$ do you think MS and others have lost through the years due to piracy? And how about the working-stiff writer and other employees? Do you think their pay could have been a little higher if it weren't for piracy?
And while I'm at it, how about OS Keys registered in the BIOS? Less piracy. Remember, legally it's their software. We buy the license to use it.
And why the concept of 8 running like a VM? Deeper UAC? Deeper file/folder ownership? Safer. Harder to hack into and pirate I would guess.
Bottom line -> No more Mr. Nice Guy MS. Times are lean. The market has changed demanding mobile and touch. Societies are mobile these days. You'll get the OS they envision it to be. You'll get MS Mail app, People app, Photos app, and some games as we have in the past, but that's it. Buy the rest via the Store.
MS saw fit for a change. It is what it is.
Oh that old Hippie! He's got some strange ideas, doesn't he?!!
