Interesting read, but something i found humorous was his comparison to an unsuccessful release and the current status of some of the dying breed cell phone manufacturers...Apple would literally have to release 2 or 3 more MIRRORED iPhone's in order to start being afraid of becoming part of that dying list, it's not going to happen with one bad release (because to be honest, they haven't HAD a bad release yet!)
The 4S and the 3GS were basically enhancements...and sold like wild fire. If they take this new iPhone and enhance it again, it will also sell like crazy (even if they left it the same size). He has a point with the market becoming more competitive, but the bottom line is, the leader of the pack is still Apple, and with such a loyal following, it would take a lot to knock them down to obscurity over the next 5 years or so.
