ZDnet have just published a review of the new O2 XDA Argon device.  

I think this device is suffering an identity crisis where many customers are struggling to see the innovation in it compared to some of the new devices that are now coming available.  The reality of the Argon is that it is targeting a different customer to the individual user. 

The Argon is really filling a gap for many customers of a basic Windows Mobile device with a a fairly large screen.  Most new devices are getting smaller or bigger and there has been a lot of demand for a 3.5" screen device with GPRS integrated.
