hmm, i assume you and everyone in your family owns a minimum of one apple device, no? when they become obsolete are you going to transition to an android phone and to an android tablet?
while apple may not be at the forefront of innovation, they do have extreme loyalty, a "lock the consumer in" ecosystem that is hard to break out of, and they've built up a brand that commands great margins.
i'd be shocked if apple isn't still a market leader in smartphones/tablets 5 years from now.
