This is a very interesting article and I could not agree more:
Not only is Apple at risk for a redo of the PC days, but I feel they somehow do it to themselves by attracting a lot of people in a high price niche market but they always on keeping their ecosystem very closed. So either you buy into the whole apple world or you drop out and have nothing to do with them.
At first it works magic, they trap consumers and keep them in their environment. But as alternative become a lot more attractive price wise, they lose the grip they had and people start breaking away.
Apple will always have a core a die hard fans, no question it. Even in their darkest times, they had a following. But I feel they are at risk of losing the masses to alternatives if they don’t open up more.
