Without an emulation mode you couldn't run old software. So basically the only way you could install anything was to install it from the software shop that would be curated with apps that were compatible for the OS/Hardware combination. They didn't want people to think they could install their personal photoshop version, so they prevented it from running any app not installed from the shop. It was cool in a way. It was a nice shot at Intel. "Hey wey recompiled Windows 8.0 for ARM and look at how well it runs". But the benefit of Windows is it's unshackled and highly supported nature. Neither of them applied to Windows RT. This is what made the Surface 3 so great though. It's a "premium tablet" at $400-$600. That is a fully unlocked Windows that can run anything (even if it's kind of slow at most stuff). Making a consumption device a temporary or weak productivity device. Apple sees that as well which is why they made the Ipad pro, but I think they went the wrong way. It's an attempt to take an OS built around consumption and build tools for productivity around it. In the long run it might pay off, but it's going to be a weak counterpart to a system even running OSX let alone Windows. MS's next move with emulation on ARM is a nice next step. But it won't help unless it can run all X86 code and not just 32bit. Whomever pulls that off wins. Then they can scale out their selection by requirements and not infrastructure as well. I have to think Apple is close, but they are probably waiting till they are absolutely sure moving the normal consumer products over to ARM is the best move. People need OSX on ARM not a Macbook running iOS. The other solution is constant erosion of the PC. As more services get moved to cloud based computing services or side developed with mobile services. The general user even in a business setting will get closer and closer to not needing a PC. Makes me think of the days were we thought we were getting close to just docking our phones and doing work with a keyboard, mouse, and monitor connected to our cell phones. The closer we get to that the more ARM or atom/cat system becomes a strong driver to kill what we know of as computing (like the snarky girl in the Ipad pro commercial asking a what a computer is). Engineers, mid to high level productive environments, servers, and enthusiasts they would still use X86 for a long while, though we might see a increase in cost of managing these systems.
