I am looking forward to purchasing one. The reason it may not have been mentioned is because it is not on sale yet. Apple is definitely going to reach their goal of selling 10 million units before the end of this year. They sold 6 million iPhone 1.x's to date, so another 4 million, with 70 countries of availability ...
Apple has changed the cell phone business, and looking at the new product, and watching Steve's presentation it will continue to do so for years to come. I am happy they added in ActiveSync support, many a company will now be more than happy to purchase iPhones for employees over Blackberry's.
I have played with the SDK and I have to say it is an absolute blast to program in. There are things that were showcased though, which I could NEVER imagine writing on a mobile app. How long until we see GTA for the iPhone? The medical programs they showcased were absolutely awesome as well. Apple seems to have a device and SDK on their hands that allows the enterprise to do exactly what they need to do, from a mobile device.
From a network security perspective, I am really happy they chose to implement VPN right on the phone, along with a host of other options for the enterprise. The remote wipe feature has been part of Blackberry's for a while now, and is an awesome way to protect information that may be stored on the phone. Contacts, emails and others. I just hope that all the third party libraries they use in the making of OS X for the iPhone have been properly updated and are not vulnerable to any exploits right out of the gate.
Apple needs to take security vulnerabilities more serious and start working with the community at large. To date they have not really done so, and it has pissed many security researchers off, people who only wanted one line of credit, but instead got none.
The iPhone 3G, I want one, and I will get one. Maybe. It depends on how much AT&T wants for a subscription with unlimited data transfer.
