I thought RT was just an ARM port, not a rewrite?

Close, but not quite. The first sentence on the linked article says:

"'WinRT' redirects here. It is not to be confused with Windows RT."

So "Windows RT" is an ARM port of the Windows 8 OS, while "Windows Runtime" aka "WinRT" is an API for "modern" Windows applications.

To be clear, I was responding to OP's literal "Windows RT" mention in my parent post.

Well, it's both I guess, it's designed to only run WinRT Store apps, not Win32 (Although Win32 is somewhat ported as Office runs on it), but that's the general idea, to break with the past. But the only reason people use Windows is The Past
