Many people thought they'd be doomed without Jobs but they've seemingly been doing just fine still (ignoring many valid criticisms here, of course, but talking about the general population).
Which I really find fascinating. Aside from their arguably better stance on privacy, I don't really find there's much at all to love about Apple products beyond they look quite nice, generally. In fact I actively dislike a lot of the way they dumb down interfaces, but I acknowledge that's something the vast majority of users won't ever care about.
Is that really all there is to it? The consistency of aesthetic is enough to win? I've always found it to be an interesting question, why they continue to be so successful.
