The only killing feature a WIn RT brings is the Microsoft Office. It will be interesting to wait and watch how well these apps run on a Windows RT based device, there are already some fumes coming out of it, but will have to give some more time to get some concrete FEEDBACK. Looking forward for positive feedback....
I'm not surprised given Microsoft's moves to jump ahead of its own customers.
That said, Lenovo has already launched its product, and both Asus and ZTE have plans for WinRT.
The big question to me is whether there is much of a Windows tablet market for Microsoft or anyone. Do users want Windows apps on their tablets enough to pay the Windows OS and memory tax for them?
What edge does WinRT have over Android tabs besides a higher cost?
