I am sitting here making this entry while I listen to XM Satellite radio both on the QTEK 9100. The stereo speakers sound great! UPDATE: I am listening to XM Satellite Radio with my Bluetooth headset (Cardo Scala 500) right now at work. It is not in stereo, but I need a free ear for listening for the phone and other things anyway and just want sound out of one ear. This is so cool 🙂 Oh yeah, I am using the EDGE connection and know I could do the same thing via WiFi with the Axim, but not everywhere while I am out and about. I have not seen any buffering after the initial loading with the EDGE network so far.
I also like the ability to use the excellent Smartphone GPS applications on the device. There are a few annoyances (primarily with dialing in portrait mode), but I am confident that Xda Developers will figure out ways to customize the device.
