Hope i don't piss off too many people here... Nicer screen, faster, hd video, multitasking... okay, is that it? that stuff sounds sweet, but I am seriously debating canceling my iphone 4 order because I'm starting to feel like it's not worth it. My iPhone 3G is still chugging a long beautifully. practically, i don't see a huge upgrade. I'm almost tempted to swap my iPhone 4 order for an ipad to experience that. What am i missing and what were you reasons to upgrade?
