Well, the first major update is out. It brings some cosmetic changes to the iPhone, and fixes a few glaring issues. The ability to purchase tracks on iTunes is great, and I can see iTunes going a long way with this. For example, if Apple could get radio stations to have some sort of standardized 'now playing' list in exchange for money or shared revenue or something, perhaps one could buy a song that one heard on the radio and liked. That would be a much more dramatic tie-in than say, Starbucks.
