Android exists. Samsung is on Apple's heels. Now that Steve is gone I'm seriously considering how long will Apple be able to keep it up so I would not worry too much. Tim Cook is just another business guy, no comparison to Steve Jobs the artist, visionary, distortion field inventor, (and yes an ass*hole too but that is OK because he gave us the iPhone,iPad,Mackbook,iPod). I don't envy Tim Cook, he took over Apple at its peek and without a strong vision he will probably rule over its decline (I hope I'm wrong).
