The problem is at the time of the OP Microsoft had said virtually nothing about Windows RT and Windows 10. Very soon after MS held the Windows 10 event and even then what was said was very much an aside comment, very guarded and contained little detail. As of today about the biggest glimmer of hope is the fact that there will be a Windows 10 for the Raspberry PI, also an ARM device.
Those of us used to the RT limitations would hardly expect Windows 10 RT to be fully functional, it is the dearth of detailed information from Microsoft that is the problem, quessworks by commentators is not enough. Yes the Answer is wrong and should be withdrawn, that is down to the mods.
