Apple is running out of ...
revisions or 'upgrades'. and they won't be able to sustain their drip-drip annual upgrades and money-raking operations.
They have to fight the competition as Android & WinMob cell handsets will offer so much more variety, tailored more closely to peoples needs.
The Far East, for example. needs waterproof units and only Android has them (if you don't believe visit Singapore or the Indochina region in the rainy season) and dragging a Zip-lock bagged iFone out to use is so degrading.
Some people love to spend all their waking hours on social networks, and they have their socially enhanced handsets, others need more business oriented units.
What needs revamping is the US patent system so all these artificial blocks to progress are eliminated. They are considering rolling back auto patent lives so maybe this will spread to other areas of technology.
The Apple/Samsung trial was an aberration, the judge bent so many rules that another trial is warranted.
