No Touch Screen: If you want both a laptop for writing papers and a tablet for taking notes in class or watching movies in bed, you'll need to buy both a MacBook Air and an iPad. By contrast, the Air's screen can show only 66 percent of the gamut, which means duller images. The Dell XPS 13, our favorite consumer laptop, is available with a 1920 x 1080 or 3200 x 1800 display that can reproduce either 93.6 or 105.7 percent of the sRGB color gamut. By contrast, the MacBook 12-inch and MacBook Pro 13-inch have panels that output at 2304 x 14 x 1600, respectively. Lackluster Screen: The 1440 x 900 display on the MacBook Air isn't as sharp as those on other MacBooks and competing PCs.
