Engadget - While the Xperia U might appear to be the next one down from the P, better battery life and general performance make this a worthy consideration if you have an eye for a smaller phone.
GS writes An Ice cream sandwich update has been launched for Xperia Sola, Xperia U and Xperia Go. For Xperia Sola users, they will get a new feature known as Glove mode. The Glove mode is best for those, living in the sub zero temperatures and now, they don’t have to remove the gloves in order interact with the phone.
TheVerge - The Xperia U is the final piece of Sony’s NXT series puzzle. In March came the flagship Xperia S, a good device that shipped with outdated software. It’s only just been updated to Android 4.0. Our verdict? It’s not thinner, faster, stronger, or in any other way better than the pack. Next up was the Xperia P, a mid-range device that really impressed, but was difficult to recommend running Android 2.3. Now the Xperia U is here, presenting itself as an entry-level option for those looking for flagship qualities on a tight budget. Think of the Xperia U as Sony’s equivalent to the HTC One V — just as the Xperia P and S were pitted against the One S and One X.

That’s in keeping with the new square design which moves a away from the ‘human curvature’ organic shape. Personally, I like how solid the U feels in the hand, and the size helps make it easy to find in the most voluminous of bags."
