FWIW, I think the Surface RT is clearly a turkey, but it's still early days and not many people have seen this yet. Windows 8, to me, is clearly a turkey on the desktop, but I'm willing to give it a "wait and see: on tablets and smartphones.
I've called the Surface RT strictly a developer and early adopter device. I wouldn't classify it as a turkey, because this is clearly where the future of the Windows platform is headed. You can put Windows 8 and Surface RT in the same position that Windows NT 3.1 occupied 20 years ago.
