It's almost as if they can spot an emerging trend quite well (the move away from floppy disks, the ubiquity of USB and downloading software, music and video rather than buying physical media)
Obviously, it works for them. An important, if sometimes overlooked, factor of their strategy is that it's not just borrow and iterate, it's a) identify device that will blow up, b) borrow well before it blows up, c) use that lead time to iterate and leap-frog the competition in polish, and d) release right as the market is poised to accept the new device as mainstream.
They can also misjudge any one of those items a bit and still power their way through, especially now that they have such credibility.
Had they not been bought by NeXT (which is what actually happened) and we wouldn't be talking about Apple setting industry designs.
