For those of you desperate to get your hands on the HTC Excalibur or T-Mobile Dash - There is an excellent review with a Video at CNET.com.
The review gives it a very positive 8.0 out of 10. It calls the device a Q Killer - but why would we want one Windows Mobile device killing another one? Surely this is about choice, particularly as the Q is only available in the US!
If you want to get hold of an Excalibur - Expansys expect to have stock of the HTC S620 within the next day or so - you can order one HERE
