Is it me or are the new macbook air's slower than the last generation? i.e. 1.8GHz (up to 2.8GHz with turbo boost) of 2012 vs the 1.3GHz (2.4GHz with turbo boost) of the 2013 models. Could it be that the macbook air's were getting too powerful, so powerful that they were matching macbook pro's for performance? For example, my i7 2.0GHz outperforms the base macbook pro retina 13" (with turbo mode on both models active) and is on par with the higher spec one (again, with turbo mode active on both models). Did apple reduce the speed of these processor's to save battery life and market it as an ideal laptop for somebody who is constantly on-the-go?
