That's a lot of interest in something that's only truly meaningful to one group of people - developers. But I see where the anticipation comes from.
As a consumer, I'm just as excited by this release. When I first started playing with the iPhone, I said that it feels like a computer that happens to make phone calls, not a phone with some additional features. The promise of great native applications by some of my favorite Mac developers reinforces that feeling.
The iPhone is quickly becoming my favorite Mac.
