It would be nice if it ran natively, but knowing Microsoft lazy asses they just ported a bad 8086 emulator to the Lumia platform and rewrote a minimal part of MS-DOS so only their versions can run, and you can't upgrade or edit system filescause they've locked it. Dammit, Microsoft. I want to see NT4 running there, NATIVELY. Emulation on Android already runs like the wind (there is also a very good qemu port, see Limbo).
