Appears that Sony Ericsson have made inroads optimizing the X10 Android phone for its 1GHz Snapdragon processor. The pre-pro handset shown earlier this month ran the Rachael interface in slow-motion, but this new prototype looks much more responsive.

In case you missed it, the XPERIA X10 got official overnight. Besides the 1GHz Snapdragon processor and big 4-inch capacitive touch display, it's Sony Ericsson's beautiful Rachael interface sitting on top of Android that impresses. Take a look:

With a 1GHz Snapdragon chip from Qualcomm, 4-inch capacitive touch display, an 8.1 megapixel camera, and the lovely Rachael Android UI, the Sony Ericsson XPERIA X10 will be a great 2010 entry into the Android market for Sony Ericsson.

I like Android and all, but one thing the iPhone absolutely kicks every other smartphone's ass at is media playback—until now. This video of Sony Ericsson's "Rachael" Android UI shows its media capabilities, and it looks un-freaking-believable.

Sony Ericsson has something cooking for November 3rd, and we're thinking it's the XPERIA X3, complete with that beautiful gesture-based Rachael user interface on its 4-inch screen. It may even have a 1GHz Snapdragon processor and Android 2.0. [Sony Ericsson]

Electronics shop Expansys has all the specs on the Android-based Sony Ericsson Xperia X3, large photos included. It looks amazing: 4-inch 800 x 400-pixel touchscreen, 8MP camera with LED flash, VGA video recording, and the yummylicious Rachael user interface. Want.

We're usually excited to get clued in on new product launches, but this vague tease from Sony Ericsson doesn't help us out much. Is it the Rachael? The Kiki? Release dates for some boring old feature phones? Something else entirely?

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.

Mobil's dug up these photos of the XPERIA Rachael, supposedly their first Android phone. Exciting, since I love Sony Ericsson hardware.
