Pha already gave you a hands on with the Trax, but for the rest of us, the phone is officially out in AT&T stores for you to play around with. Some of the features that make the Trax worthwhile include touch-sensative music controls, media playback for MP3, AAC, and WMA files, HSDPA for fast-as-hell ‘net access, and 1.3-megapixel snapper.
Where the Trax really shines though is through music. You can download MP3s on the go from eMusic and can listen to streaming XM radio as well. Not too bad! The Trax also supports the recently announced AT&T video sharing service.
All the standard stuff like stereo Bluetooth, IM clients, image editing, etc. are all there as well. For $130 (with a two-year contract), it seems like one of the best well-rounded phones I’ve seen in a long time.
