Originally unveiled in March 9, 2015 at Apples "Spring Forward" event, the (new) Macbook featured may changes from its predecessors. This included a retina screen, haptic feedback click motor within the fixed track pad, and a USB type-c port. I have enjoyed this machine thoroughly as it is now my only home computer.
While at work I use a Retina Macbook Pro and a Das Keyboard Model S Ultimate. Mechanical keyboards have quite the following and seemingly infinite levels of customization and pedigree. While I do not do cool backlit customizations, I do greatly enjoy the feel and responsiveness of a these keyboards, and especially that of the Das Keyboard.
Unfortunately for me, out of the two aforementioned products… never the two shall meet. The Macbook is nice and is definitely well suited for "real work." However the keyboard begins to strain your hands, the longer you type, and makes extended typing difficult/impossible. Currently the USB type-c connector is so new that there are no mechanical keyboards with this type of connector, but at least I have butterfly mechanisms… sigh
For more info on the Macbook you can find a relatively comprehensive review on The Verge, but as with all Apple products you should probably wait for the next one.
