By now, I'm sure most of you have at least heard the news that Apple has unveiled its long-awaited iPhone yesterday at the Macworld Conference in San Francisco. This article from THE Journal does a nice job of explaining the phone's many features and the ways it's unique from other smartphones. In addition to a larger screen, iTunes, the ability to run Mac OS X, and Google features like Google Maps, the phone has a built-in sensor "for dimming the display and disabling input when the phone is placed to the user's ear", which saves battery power. All very cool, and of course, it looks scrumptious. I think the iPhone, which will be available only through Cingular starting in June, won't cause current Blackberry, Treo, and Sidekick users to defect immediately, though if it is as good a product as the iPod, it'll could well tempt those of us who've never had a smartphone to test the waters.
