ZDNet:

If 6.4 million MacBook Airs sounds unimpressive for a full year’s sales, put it in perspective: Gartner estimates that only 22 million premium ultramobiles were sold in all of 2013. That gives Apple nearly 30 percent of this fast-growing market, which Gartner forecasts to grow by roughly 50 percent this year and more than 70 percent in 2015.

It’s also a profitable segment, with average selling prices of $1000 or more.

I plan on buying a MacBook Air once it gets the Retina display.
