People will always buy XXXXX simply because it's made by XXXXX.
(Okay let's insert Sony, BMW, Dom Perignon) Doesn't mean the product is good/best but it might mean they've had a good track record at one time or another.
It's not problem for Apple, it's every companies dream. Apple happens to execute things well as a whole. Are there exceptions, absolutely but their track record of innovation, creativity, quality and ease of use is exceptional.
FYI: I put Sony in there as many people years ago would buy Sony simply because, but I know that has changed.
