Total speculation follows.
This weekend, I was at the Apple Store, and managed to get into a rather in depth conversation with someone, who, well, really knew their stuff. More so than other store employees I’ve chatted with, and some of them were pretty good.
I was passed the observation that an interesting “event” had occurred rather silently.
They ran out of iPhones.
This person explained to me that Apple does a really good job of keeping them stocked, since they were a major supplier for the area. However, they were clean out.
The only times that ever happened, was when Apple was about to change inventory on them. Killing the 4GB model was one. Going to the 16GB was the other.
A 32GB or 64GB iPhone seems likely, as iPhone customers want as much memory as an iTouch allows.
This would be a good time to add additional gestures, which, incidentally would help out with the lack of cut’n’paste.
But the real feature I’m looking for? The ability to push my contacts to other people with an iPhone. We’ve got the same device, the same applications, the same data, and bluetooth, there’s no technical reason I can’t give someone my ‘electronic business card’.
