Announced this week at WWDC, the iPhone 4 is a nice evolutionary shift from the 3GS.  Though it's the same design we've seen in rumors and leaks over the past few months (hey, thanks for that, Gizmodo), new features like FaceTime video calling and the Retina Display make it worthy of consideration by iPhone fans and first-time smartphone buyers alike.  Keeping that in mind, I ask you - does the new iPhone 4 appeal to you, are you holding off for the next revision, or are you so firmly planted in your respective non-Apple platforms that you can't fathom a switch?
