An ardent defense of Windows RT, followed, inevitably, by a lively discussion thread, but I doubt any of this will be solace to Surface (non-Pro, < 3) customers who now have dead-end devices
"The long and short of what is happening with Windows RT is pretty darn simple:
Windows RT: Did it really die? Absolutely not and here's why
- Microsoft (Surface and Surface 2) and Nokia (Lumia) branded ARM-based tablets will NOT be getting a formal update to Windows 10. They will be entitled to limited subset upgrades of Windows 10 functionality, but will not be given Windows 10 as we know it.
- Windows RT as its own SKU, or brand, of Windows will be going away (naturally).
- Windows RT's combined direct spiritual successors are the Windows 10 Mobile and Windows 10 IoT SKU lines, which work on devices under 8" in size and DO feature ARM processors.
- Windows 10 Mobile devices will not have access to "desktop" mode, and as such, lack of any proper x86 app support."
