Windows is more than just the ability to run Win32 applications, though. I think what Ivan was getting at is this is a fully-featured desktop-class OS and not an upscaled smartphone OS. Its multitasking abilities, for instance, blow away anything iOS or Android can currently do.
You've got complete access to the file system and full network file sharing support. Local storage? Cloud storage? I'm sharing terabyes of data over my local network just by adding a shared network drive and adding it to my libraries. Chucking data back and forth over the network instead of mounting it like an external drive is great. This is a computer, not a peripheral.
Then there are the sort of peripherals the platform itself is capable of supporting. I managed to get hold of a Windows RT driver for a USB Ethernet adapter and connect it successfully to my Surface. The platform is being tightly-controlled by Microsoft, but at its core level, it is as extensible as regular Windows. The smart folks over at XDA developers are already close to working out how to recompile Win32 applications and install them under Windows RT.
It really is full Windows, just on an incompatible platform with x86. Its no different than Windows Server running on Itanium processors or back in the good old days, I had to look after some NT4 servers running on DEC Alpha processors. You couldn't just install x86-compiled Win32 apps on them either (though Itanium would actually emulate x86). They weren't any less Windows because of it, though.
