Well, it looks like my prediction of a super-attractive voice/data plan was wrong, while others who predicted that iPhone users would be raped by an overpriced plan were also wrong. The end result is that they're touting these "special" plans which are really no different than their standard voice plans with the $20 smartphone unlimited data plan. Could've been better, could've been worse.
Some fine print on the AT&T site has also been mentioned elsewhere which suggests that the iPhone's iPod capabilities will be disabled on non-activated phones. I'm still waiting for the official release (or an official announcement) to see if this is true but, if so, it would also prove false my guess that the phones might be fully usable as internet tables/iPods without ever being activated. Still, it doesn't surprise me, either, and the market of people who would want to buy/use an inactivated iPhone would have been pretty small anyway.
On a positive note, it looks like I was right that existing AT&T customers could buy the iPhone without having to worry about getting out of their existing contract or extending their current contract by another 2 years.
So at the end of the day, it looks like not too much has changed since last week. For the majority of people, the iPhone will look just as attractive or unattractive as it did to them last week.
The one outstanding question I'm most concerned/curious about is whether the virtual keyboard can be used in landscape mode.
