Sony Ericsson Satio is still the best camera phone on the market even with the release of Xperia X10. Satio has got Red Eye Reduction and Touch Focus but these two functions are missing from Xperia X10. In addition, Satio is using LED Photo Light & Xenon Flash which allows photo taking in poor lighting conditions while Xperia X10 is using Photo Light only.
Satio has the combination of the Cyber-Shot Camera Phones and Walkman Music Phones. Previously Sony Ericsson has market them as 2 different types. Satio is a 12.1 Megapixel camera and the camera recharges quickly so that you can takes one photo after another. This is an advantage over the Samsung Pixon 12 M8910 slow charging camera. It also equipped with Best Pic, Smile Detection and Photo Fix.
Satio also has the function of Walkman Phones. I assured you will be happy with the music quality. But the main defects about this is the missing 3.5 mm jack.
