From Apple’s official press release:

Apple® today updated MacBook® with the latest Intel processors, improved graphics performance, faster flash storage and an additional hour of battery life, making the thinnest and lightest Mac® better than ever. Featuring an all-metal unibody enclosure, MacBook is now available in four aluminum finishes — gold, silver, space gray, and for the first time on a Mac, a gorgeous rose gold. With a stunning 12-inch Retina® display, highly responsive full-size keyboard, Force Touch trackpad, versatile USB-C port and all-day battery life in a design that is just 2 pounds and 13.1 mm thin, MacBook is the future of the notebook.

And:

The updated MacBook features sixth-generation dual-core Intel Core M processors up to 1.3 GHz, with Turbo Boost speeds up to 3.1 GHz, and faster 1866 MHz memory. New Intel HD Graphics 515 deliver up to 25 percent faster graphics performance, and faster PCIe-based flash storage makes everyday tasks feel snappier.

It’ll be interesting to see the benchmarks on this new version. I’d love a cheaper machine that can handle smaller Xcode builds and lightweight rendering.

And now with up to 10 hours of wireless web browsing and up to 11 hours of iTunes® movie playback, MacBook is the perfect notebook for all day, on-the-go computing.

Interestingly, as of this writing, the Buy link leads to a page with this message:

The page you’re looking for can’t be found.

I suspect that will change soon.

The Buy link is now up.
