Good set of questions. My takeaway from yesterday's event is that Apple is playing to win in the Smartphone business, which is good since they have some formidable competitors out there.

The second takeaway is that all these cool iPhone apps are going to run on the iPod Touch as well, which means that Apple just tightened its grip on the high-end media player market. If you're Microsoft, what is the answer to the iPod Touch? The Zune was designed to compete with the Classic iPod. Do they just flush the Zune and come out with an MP3 player that's running Windows Mobile? Keep an eye on that one.

The likelihood that the iPhone will be on Verizon or Sprint is very low since they use the CDMA standard and AT&T (as well as most of the rest of the world) uses GSM. TMobile is GSM so that's at least an outside chance the iPhone will eventually show up there.
