New Mac Mini and Macbook Air computers now available in Apple stores feature the Thunderbolt feature, it's this souped up version of connectivity, think of it as firewire times a billion. They also have the Intel Core i5 processor, nicknamed Sandy Bridge.
Here are the specs from Ars Technica if you like specs:
The lowest-end 11-inch MacBook Air sits at $999 and has a 1.6GHz Core i5 processor, 2GB of RAM, and a 64GB SSD. That goes all the way up to the highest end 13-inch machine at $1599, which gets you a 1.7GHz Core i5, 4GB of RAM, and a 256GB SSD. (All come with Intel HD Graphics 3000.) And just like the rumors said, the Air's backlit keyboard has made a triumphant return with this update, after mysteriously disappearing for a while.
In addition to the new MacBook Air, Apple also updated its Mac mini line with Thunderbolt and Core i5 or i7 processors (bumped from Core 2 Duo). The updated machines also lack an optical drive. The low end starts at $599 with a 2.3GHz Core i5 processor, 2GB of RAM, a 500GB hard drive, and Intel HD Graphics 3000, while the higher-end non-server version starts at $799 for a 2.5GHz Core i5 processor, 4GB of RAM, a 500GB hard drive, and AMD Radeon HD 6630M graphics. Mac mini with Lion Server costs $999 with a 2GHz quad-core Core i7 processor, 4GB of RAM, dual 500GB hard drives, and Intel HD Graphics 3000.
All the new machines come with Lion, the latest operating system, pre-installed. Other Mac customers can buy Lion in a box (Help! Someone put a lion in this box!) or download it from the Mac app store.
