How the Surface Pro stacks up. MBA 11" Comparison.
MacBook Air 11" compared to Surface:
Its 27% fatter (17 vs 13.5 mm)
19% heavier (2.38 v 2 lb)
Gets less battery life (~4 (Anandtech) vs ~4.5 hr (Speculation))
Doesnt have a touch screen
Doesnt have an active digitizer/stylus
Doesnt have a detachable keyboard (Pro or con...)
Doesnt have 1080p display (1366 x 768)
1 vs 2 cameras
It gets throws around a lot that Microsoft failed with the Pro, but to me it looks like they did pretty good for what it is. Sure, people expect stellar (8+ hr) battery life from tablets, but thats why there's always Clovertrail or ARM Windows tablets.
