Well, I got the infamous iPhone after both my 3rd gen iPod and 4 year old cell phone went to a better place. I don't really have anything new to add to the conversation but have to say if you love your mac, the iPhone is essentially your pocket sized extension of it. You can carry a pocket sized portion of your music library on it, do a pocket sized amount of work on it, and stay connected with email and maps.

Favorite feature? The seamless syncing and integration. Snapping a photo and emailing it right off to mom is pretty neat. So is blogging from my phone :)
