A new line of hardware was just announced today at Apple WWDC 2012. The first announcement was the new MacBook Air, which has Ivy Bridge processors, up to 2GHz dual-core i7, up to 8GB of 1600MHz memory and 60% faster graphics. It also has 512GB of flash storage and two USB 3.0 ports! The 11-inch model features a 1366 x 768 display, and the 13-inch model has a 1400 x 900 display. Pricing starts at $999 for the 11-inch and machines start shipping today.
There’s also been an update to the MacBook Pro. Ivy Bridge processors, up to 2.7GHz quad-core i7′s, 8GB of 1600MHz memory and 60% faster graphics here, too. The 15-inch has Kepler GeForce GT 650M, up to 1GB of memory. All MacBook Pros have USB 3.0. The MacBook Pro comes in 13-inch and 15-inch. 13-inch starts at $1199 and the 15-inch starts at $1799. Also shipping today.
The big surprise is the next-generation MacBook Pro with Retina display, which also starts shipping today! The next-generation MacBook Pro has a 15.4 inch display with a pixel density of 2880 x 1800 (four times the number of pixels than the previous generation of MacBook Pro).

Price starts at $2199 for 2.3GHz quad-core chip, 8GB of RAM and 256GB of flash storage. The next-gen MacBook Pro goes up to 2.7GHz quad-core i7s and up to 16GB of RAM and 768GB of flash storage. At 0.71 inches thin (almost as thin as a MacBook Air!) and 4.46 pounds, this is the lightest MacBook Pro ever.

Ports: SD, HDMI, 2 – USB 3.0, MagSafe 2, Thunderbolt and a headphone jack. FireWire 800 and Gigabit Ethernet Thunderbolt adapters. [Nota bene: the unibody is now an actual component of the display and not just a case, which reduces the number of layers and integrates the glass right into the frame, making it thinner.]
