Nearly Everything hardware on the phone I love, feels right, great screen, good sound, nice size and weight, just the power button being flush I don't like but can live with.
Software - oh dear god, Sense5 is like android aids especially blinkfeed. 4.2.2??? Silly dock thing. Just gumph the phone doesn't need, just GIVE US BASE ANDROID.
In a perfect would I'd have my Nexus 4 in the 'One' hardware, suppose i'll have to wait for a hacked ROM and it can sit in it's box for now.
