The keyboard on the 12-inch laptop is excellent if not different from prior models, it may take a little getting used to but it does provide a crisp “clicking sound” from all of your keystrokes.
The Retina screen is quite spectacular and extremely bright to look at, while the very thin bezels can make your screen actually appear bigger than it really is.
The MacBook is a very portable unit for sure, and Apple has successfully created a fanless Mac, running as quietly as your iPad. A unit well worth investigating !
