Apple wasn't just showing off fancy watches today -- it also unveiled its new MacBook (check out our full hands-on here!), the first major addition to its ultraportable line since 2010. And yeah, it seems like it was worth the wait. Shaving off even more from the MacBook Air's already thin design, the new MacBook features a sharp 12-inch screen with a "Retina" 2,304 by 1,440 pixel resolution, as well as a thin bezel around the screen and keyboard. It's just 13.1 millimeters thick, around 25 percent less than the 11-inch MacBook Air. The new MacBook brings the best of both worlds from Apple's past laptop lineup: a tiny portable case like the 11-inch Air, and a larger, high-res screen like the Retina MacBook Pro. In short, it seems like the ideal Apple laptop -- something it's been working toward since Steve Jobs slipped the first Air out of a manila envelope in 2008. The MacBook ships on April 10 and starts at $1,299 with a 1.1GHz Core M processor, 256GB SSD and 8GB RAM. There's also a slightly more powerful model for $1,599 with a 1.2GHz processor and 512GB SSD.
