Jason Snell, after outlining a bunch of problems with the original MacBook Air:
And yet my affection for the MacBook Air was legitimate! It was so much thinner and lighter than any laptop I’d used before. It felt like the future. And the truth is, this is the biggest legacy of the MacBook Air: It predicted the future of laptops and then brought that future into being. It created an entire category for PC laptops, Ultrabooks, which was loosely defined as “PC laptops kind of like the MacBook Air.”
