Just to make sure you guys have been paying attention, the T-Mobile G1 does NOT have a 3.5mm headphone jack which means all your music will have to be either routed through an adapter or use a proprietary ExtUSB headset. Obviously, this blows big time but it does go along with many other HTC products (just not the HTC Touch HD) so it's not exactly from left field. However, it will be interesting to see if this affects sales at the Amazon MP3 Store for the T-Mobile G1 or will people just fold and use whatever headset HTC provides? I can't imagine people buying music if they can't listen to it the way they want to.
