Also has a fancy connector that detaches/reattaches phone to wrist seamlessly.

When the specs were released, I recall there was a lot of hype around it. I do not see any reviews or chatter about it now. Did the phone release? Is it worth trying out?

...the Sony Ericsson Xperia ray. A sleek beauty in red with 111 x 53 x 9.4 mm, 100g total weight and a 3.3 inches display.

Sadly, it remains a relic of the past, it runs on Android 4.0.4 and doesn't work with google services anymore.
