Whats an IMS device?
The optimist would say that an IMS device is a SIP-enabled terminal, a dual-mode phone (CDMA or GSM, and Wi-Fi or WiMax) or an IMS client framework in a device to which a user can add IMS-type applications. A pessimist would respond by stating that they dont know what an IMS device is, because they havent seen one yet, or that out of curiosity they would buy one, if only they could find one.
