Clearly Apple is not as strong now with SJ gone, but in trouble? come on, with the cash they have they can reinvent themselves a hundred times and still come out of the pile of **** smelling like roses. Doomed is nothing but hyperbole to sell books/blog clicks etc...
If Samsung, HTC, LG etc... etc.. etc.. can copy Apple and make a go at it, Apple sure as hell can have some years to "find it's new direction". Hell the fall out of a stagnate Apple is it will cripple the copy cats as they won't know what to build. We have already seen HTC try to build something new and creative with the HTC One and their financials show how well that went. Samsung is the only company with solid financials that might have a chance to fly on it's own if Apple doesn't show them what the "next big thing" is. Once Apple shows them they will copy it, make it plastic and sell it. The true "Haunted Empire" is the slew of Chinese copy cats that wait to see what Apple is doing next.
