iPhone Mania Runs Wild

The latest round of iPhone mania kicked off yesterday with the introduction of iPhone 2.0 at the Apple WWDC.  There has been some speculation that Apple is setting it sights on the corporate market, intent on challenging the dominance of RIM's BlackBerry and Microsoft's Windows Mobile-based devices.  I've had a number of chances to play with an iPhone, and I have an iPod Touch, but I can't imagine using an iPhone as a BlackBerry replacement.  Why?  The lack of a true keyboard.  I find it nearly impossible to type on an iPhone with anything near the speed of typing on a BB.  Not to mention the lack of things like dedicated speed-dial buttons.  Still, it's hard to argue with the success the iPhone has enjoyed so far.
