The Xperia S is a superb device infact it's the best handset I've used so far. The Xperia x10 was my first ever android phone and I loved it..
The XS takes it to a whole new level. Your able to do so much with it The best part of this device is the display the colors are razor sharp and pictures look wonderful thanks to the 720p "display and 342ppi.
Camera is amazing taking full 1080p videos which actually comes out very good The memory isn't so bad even though it says 32gb mine came with 25gb probably due to pre configurations
However I was very pleased to see 1.8gb of phone memory instead of the advertised 1gb :-) The transfer rate is very high thanks to the high speed USB settings At about 14mbs write and 16mbs read
One of the main thing that I was concerned about was the battery life however it seems to be doing pretty good giving about 8-11hrs a day for me and I use the device a lot at times
In total I say it's a very good device well done Sony! By the way I'm using my Xperia S to write this review
If your thinking about getting a high spec mobile..this is the ONE! It's worth the money
