Steven Hodson wrote an excellent post describing some of the details surrounding the new Apple and AT&T agreement. He says, "Don't blame Apple for that sucking sound around your wallet." While he's right, a lot of people are looking at AT&T as the culprit. Why though? Neither company is at fault here. AT&T worked out a favor for everyone unable to afford the high initial cost of the iPhone. As a result, AT&T upped their data plan $10 a month, but what for?
I suspect AT&T is looking to protect their assets by investing more money into creating a reliable network to handle (what will be) a high influx of new contracts. How do you think they'll do with so many new people playing around with their unlimited data packages? Ask yourself, what did Apple release at the WWDC? Oh, an app store, so what does that mean? It means more data transfer. The iPhone is looking to change the way we handle mobile computing.
As the mobile user experience is refined, more people will abuse their unlimited data packages and spend less time using their desktop/laptop for web browsing. Now, wouldn't you rather support the infrastructure that is going to be responsible for transmitting all this data? The same one that you're going to be pissed at if for some reason your unable to browse the web at near wifi speeds. I know I would. Now I have to finish my paper that's due at noon.
