So what phones offer a vanilla Lollipop OS? I'm really quite sick of TouchWiz, to be honest, and the thought of a phone running Lollipop with no bloatware is too tempting. I just don't know what phones offer this. I assume the N6 does?
Nexus 6, Moto X, Nexus 5 (getting quite long in the tooth).
Nexus 6 is the complete package and one of the best phones out right now, but you'll have to consider the size. To me it felt big for a day, now it feels normal and anything smaller feels archaic.
I think this year I am going to try leaving the Nexus family for a generation. I want some solid, premium feeling hardware and battery optimizations. I won't be surprised if I come crawling back, but you never know until you try!
