Granted, without question, AAPL has been the superior investment over the past couple years. But Nokia and Motorola looked pretty good too if you take a different chunk of history. Although what AAPL has achieved is clearly more sustainable than the temporary success of Nokia and Motorola, the bottom line is they are constantly at risk of becoming commoditized. It happened with the Ipod and Ipad. It will likely happen with the IPhone.
