It's been nearly three years now since we saw Microsoft tease what they thought Surface could be. Now with the Surface Pro 3 they've been able to refine their product down to what is a pretty sweet rig. My question is, where is Apple's rebuttal? Imagine a "tablet" not much thicker or heavier than the iPad Air running a fully fledged version of OS X, with 8GB RAM and a powerful processor. Honestly I can't see why this wouldn't be an area Apple would miss. Thoughts?
