Funnily enough neither the iPad 3 or 4 were officially called that. I think they were The New iPad and the iPad with Retina.
The Surface (not Pro) is actually okay, and I suspect the 2 is even better. Like the WP8 devices, if there was any app support they’d be fine. They just don’t offer any compelling reason to be chosen over established alternatives.
The Pros should be good, given their price. I’m not surprised people like them. If I’d had the cash I’d have bought one.
