While Sony Ericsson's K810 was kinda ubergeeky with that 3.2MP camera, the K550 is  a slimmer toned down 2MP version. No image stabilization and with a fixed state 64MB phone memory you can't expand, also it doesn't features that bright xenon flash. It state to come to US this Q2. But atleast after all this short comings it still feature that nifty trackID software that can identify music you play into its mic.
