It's been just over a year since Apple launched its slimmer Macbook series. Today, the company is upgrading them with new processors (from Intel's sixth-generation Core M series), as well as refreshing the built-in Intel HD GFX, promising around a 25 percent faster graphical performance. On top of new processing muscle, there's faster flash storage and improved battery life. Apple claims you'll get up to 10 hours of web browsing, and up to 11 hours of movie playback with the new machines. However, if you were looking for more ports, you're still going to have to look elsewhere -- or splurge on a hub.
