Do you remember the mostly unknown HTC Panda I wrote about earlier? As it turned out today, it's O2 UK's new Xda Argon - a Windows Mobile 5.0-based Pocket PC Phone Edition which clearly follows in the tradition of the O2 Xda IIi (aka HTC Himalaya).
Looks like it's nothing special except the large 3.5" touchscreen and the two megapixel camera.
All the rest is pretty basic - including GSM and GPRS (no UMTS not to talk about HSDPA), WiFi and Bluetooth and - unfortunately - Windows Mobile 5.0 for Pocket PC Phone Edition only:

And since the O2 Xda Argon isn't anything special, you can get it - with a contract - for free.
