That's a whole lot of additional features you might be missing from the older MacBooks. The downside is that it makes your new laptop as chunky as the 2012 model. From a depth of around 0.6 inches, you'll now have a machine that's almost an inch thick. OWC Chief Larry O'Connor said the company has been developing the concept for more than three years. "[We] feel now is the perfect time for this groundbreaking product," he added.

The company doesn't have a release date and pricing info for the DEC yet, but it will showcase the accessory at CES this week.
