+ Fast, instantaneous Apps
+ Now many apps - except Pinterest I miss nothing
+ Excellent Selfiekamera
+ Acceptable normal camera

+ Great design without protruding lens (iPhone), without sham Karbon, neither too sensitive nor slippery.
What I miss what I's criticisms? To be honest, so far almost nothing! In 1-2 months I will possibly resent criticism.
Addendum on March 7, 2015: Today a Skype call is answered, when I was in the Wifi there. That worked great: I had not at Skype on, and the sound quality was almost to telephony standards.
