A decent camera would have been nice, but I'm not getting one until they start supporting A2DP and resolve the modem-tether issue that is ongoing! Bluetooth audio streaming is fantastic (yes I know the quality is not as good as it could be, but for ease of use you can't beat it!). I have a couple of pairs of bluetooth speakers kicking around the house, and when I want a little music I just connect the phone, fire up WMP and there we go. I find it odd that a music-centric phone like the IPhone doesnt do this, as listening to headphones/via a dock is kinda limiting for a phone.
As for modem tethering, there's a faff in the app sotre now about an app that let you use the Iphone as a modem for your laptop (vital, in my book!) It was put up over the weekend, taken down, put up & taken down again by apple.
Weird...
Maybe I'll wait until the 3rd model comes out (& what are they going to call it? Can't be Iphone 3! too confusing...)
