I was using Samsung Ace before I bought Sony Xperia E. I also got a Sony Headset free. I liked the phone when I saw it for the first time for the looks it had :). I had used W810i from Walkman series and was great fan of the sound quality that a Sony phone comes with.
I wanted a strong mobile and liked the concept of scratch free screen. My happiness died when network dropped frequently. The touch screen sensitiveness is not good enough. I have to literally press the screen instead of "touch" the screen. The scratch free screen still requires screen guard. Widgets are good, comes with built-in free apps.
I could have got a better phone with good features at low cost from Samsung. The only good thing about this phone is the sound quality. I love listening the music in this phone. Not a good buy, better get some Samsung phone with lower cost than buying this one.
