Those who don’t think that that Apple MacBook Air is the best ultraportable on the planet give that honor instead to the 13-inch Apple MacBook Pro with Retina display.
It’s pricier than the Air, but you get more powerful hardware, including a faster-still fifth-generation Core i5 processor and Iris integrated graphics that are good enough to play most modern games - albeit at lower quality settings. You also get Apple’s Retina display. It’s still terrific looking, even if it’s been surpassed a little in terms of total pixels by some Windows competitors.
