For those that don't want to read all the reviews themselves I will try to add a non biased summary:
Most if not all reviews like the build quality and think it feels and looks like a premium device.
Water resistance works as advertised.
some drop tests where done (not on concrete) and it survived without a scratch.
Reviewers like the way the screen looks but viewing angles could/should be better eg not as good as the competition, but better than previous Sony devices.
synthetic test done on 100% brightness paint a different picture, the screen doesn't perform as well as it's competition, although color accuracy is excellent.
1080p is nice especially for text but don't count on a spectacular difference with 720p
The reviews that mentioned sunlight readability liked it.
Battery is generally regarded as good.
stamina mode works pretty good .
Devices feels speedy, no hiccups or slowness.
Syntactic benchmarks find that is is faster than devices that uses the same SOC ergo very fast
Some say it's good others say it's rubbish. My take is that it depends on your taste. It is a bit soft and doesn't have a high saturation, so some would say it looks natural while others would say it looks toned down. this is something that is fixable with PS or iPhoto. I'm curious about the performance with a 3rd party camera app.
Sound/ Call quality:
speaker is average and on high volume perhaps below average.,
call quality is average
sound via earplugs/headphone for music etc is good / excellent
All reviews agree that this is the best Sony smartphone ever.
All reviews rate 4 to 5 stars or equivalent
Some reviews think it is the best smartphone currently on the market ( or at least you are able to order it) while others think that there are better phones or that it is best to wait for the new HTC/Samsung/LG etc.
