Sony Ericsson will use their own interface in their next Android-powered Rachael smartphone. The good news: It kicks serious ass. Check out the video demonstration, as well as the new images of this hot Android smartphone and the new Kiki.

As you can see in the video, the user interface in the 7.2Mbps HSDPA Rachael—which is rumored to have a Snapdragon processor, an 8-megapixel camera with auto-focus, and 3D acceleration—is extremely sleek, making full use of the touch interface, with pretty widgets everywhere. It also appears to be heavily oriented to social networks like Facebook and Twitter. I like it enough to make me want to ditch my iPhone—if it had equivalent apps to the ones I use, that is.

People were discarding already Sony Ericsson—myself included—but if they release this on time, bug free, and with this interface, they may have an opportunity to become the leading Android smartphone. [Esato via Boy Genius Report]
