When the iPhone was released, I was excited. When I saw the iPad mini and the iPhone 5, I didn't really care. I just...didn't care. If design should excite and I wasn't excited, has Apple become irrelevant or is it just me?
I think relevancy and excitement are two different things - only new, novel products generate excitement, while relevancy... Design doesn't have to excite; I think it just has to do the job well, and Apple is still doing the job well.
I suppose that the advent of Android and WP8 have made it such that Apple is no longer the only player - so perhaps it has a lost a bit of love in that way - but don't you think that plenty of people still love iPhones and iPads?
