Microsoft Announces ARM-Powered Surface Pro X

This would make for a beautiful Linux device

So no one going to talk about the removable hard drive?

Didn’t Windows RT fail? I’m genuinely curious: what’s different here?

Windows 10 now supports x86 emulation on ARM processors, so most programs will run on this device without a problem.

Unlike Windows RT, which could only run things from the windows app store.

And this isn't the first ARM Windows laptop with x86 emulation. It is just the first Surface-branded one.

Windows RT was especially hamstrung because without jailbreaking it couldn't run Win32 desktop software even if it was compiled for ARM.
