Today Apple updated the Mac Mini product line.
The Mac Mini now features next-generation Intel Core i5 and i7 processors, new discrete AMD Radeon graphics, high-speed Thunderbolt I/O, and it comes with OS X Lion right out of the box. Designed without an optical drive, the new Mac Mini can use optical drives on other PCs and Macs, and it works with the MacBook Air SuperDrive. The new Mac Mini delivers up to twice the performance of the previous generation in the same compact design.
Additional information on the new Mac Mini may be found on the Apple website.
