Bloomberg's sources suggest that Cupertino is actively working on a version of its tweaked ARM architecture that would run inside Mac PC, in particular its laptop products could stand to benefit from its battery sipping design.
Similarly, the AluBase (right), also a Wagner design, lets you stand your laptop up vertically in order to maximize your desk space, and it comes with interchangeable sleeves to fit the various Apple laptops (we actually think this works better than Twelve South's BookArc, though it's not necessarily as good-looking).
