I've never been a fan of Bluetooth, I always have problems hearing people who use Bluetooth headsets. What I do like however, while it looks corny as hell, is for hands free communication, using the iPhone earbuds. Not sure if you know this or not, but the iPhone has slightly different ear buds then the iPod does, on the right wire there is a small rectangle that has a built in microphone, it also doubles as a button that can be used to pause/resume and advance music and videos. I find it works really well especially when working out.. I keep my iPhone on the charger most of the time, while it takes no rocket scientist to come to this conclusion, if you don't do much with video and don't play games you can get some very good battery life, for an iPhone. As for music, I think you really may be missing out. Only time I use the earbuds is when I'm working out. I don't really use the iPhone as an iPod either, I have a 120GB iPod Classic that I use as my main music source, but I have all songs synched on both devices and podcasts only on the iPod. I have my iPod hooked up to my home theater system and blast my music through there, in my Mountaineer I had a dual Aux Input adaptor that I'd use for XM and Sirius, quite other I'd disconnect one of them and hook my iPod up to it to play my library on the go. I have no Aux In on the Lincoln, so I have resorted to having to use those shiny Frisbee looking things that came about in the '80s for audio entertainment. Up until recently I haven't even so much as touched a CD since 2005 when I got my first iPod. To have my entire music library in one small device is just amazing to me.
