Xperias are great
After the missus S3 started having difficulty charging (apparently the USB port needs resoldering after the two years guarantee pass), and tired of the touchwiz interface, I gave my wife the S4 and got for myself a Xperia Z1 compact. I had already got a Xperia M for one of the teenage units, and she is very happy with it, so I decided to try the "underdog".
The result is that now, besides the Z1C, I also got a Z2 tablet. Fast, with a nice fluid interface that not only looks good but doesn't get in the way, these were two great buys. The Z1C has great battery life and an amazing camera, the Z2 tablet has a great screen and is extremely fast. The included office suite has taken all MS format documents I've thrown at it without any hiccups, great for when I take it with me on business trips.
I had quit Sony for Nokia with the issues I had with the K850, then gave up on Nokia after the N96, now I'm back with Sony after trying HTC and Samsung, and if they continue with this quality level, I will surely keep buying and recommending sony androids for a long time.
