I tend to think the opposite. When you think of design you think of Apple (which in turn means Jony Ive). Whether or not they cause some functional issues doesn't matter. The market has spoken and they love the sleek design that this man has come up with. If it weren't true people wouldn't be all out copying the designs of Apple. I think history will look favorably on him, and pretty much forget the functional issues (whether real or just perceived) his designs caused.
