Next Sony Ericsson phone UI. Pretty impressive. But my reservation about super solid UI like is that it is typically restricted to the core built in applications. It’s ability to support other apps with a standard UI core library to give consistent and user friend interface is what makes iPhone successful. Nevertheless, SE seems to have picked up some lessons from Palm Pre with the integration with social applications. Still between blackberry, palm pre and iphone, it will be hard to squeeze into the playing field now especially for business users. Before the O2 mini, i was an SE fan. Had a number of SE phones and even had the Smartphone P900 for awhile. But in the smartphone arena, nokia and SE is so far losing the battle.
