According to 9to5Mac Microsoft Stores in the US offer customers US$650 if they trade in MacBook Air for Surface Pro 3.
The URL slug tells us what 9to5Mac thinks about this deal: “microsoft-is-obviously-trading-its-crap-tablet-for-computers-they-can-actually-use”.
That’s unfair. Yes the MacBook Air is a great computer — I’m writing this post on my one now.
But from what I’ve seen of Microsoft’s Surface range, including the time I spent with the Surface Pro 2, I’d say Microsoft’s tablet-cum-PC is the nearest competitor to the MacBook Air and it’s not that bad. For now, it is the only serious alternative.
