End of the PC? No, iPhone is the end of the cell phone
It's a longshot, but if they succeed the cell industry will be soon shrinking rapidly into irrelevancy. All that wasted money! Too bad because all things will be Internet Protocol-based -- the best true convergence. The Wi-Fi spots today will burgeon and blossom via new WiMax meshes, and later via satellite-based Internet canopies (for higher "roaming" cost, for sure). Your PC and iPhone (using the same guts and GUIs) will hop along an IP constellation, with certain "visitor" fees applied but no single-provider lock-in.
