Well it was actually quoted by Apple that prices of MacBooks will rise by £500 due to BREXIT. So yeah its all tied in to the currency in the end.
But the way I see it, is that there is no innovation like it used to be. Markets are becoming stagnant with little competition, and the best way to keep profits rolling is to limit our options, be it proprietary design, or small incremental increases.
This, In reality they didn;t have to raise the price so much but Apple are incredibly greedy as they know saps will pay anything to have an Apple branded netbook......I mean laptop... ^_^
