I don't use android devices but the reviews of the 6 on youtube eVEN with 8.02
are saying its the best phone, period.
Maybe that is a bit over the top but its as you said, 8.02 is far from unusable.
Yeah it's been totally fine for me. There is obviously some optimisation that is always welcome but compared to 7.0 it is a dream. It feels almost the same as 7.1.2 to me apart from some areas, mainly safari on the iPad. Nothing major and a pretty trouble free upgrade for me, ignoring the epic fail that was 8.0.1.
8.1 will bring the Polish in the smaller details that Apple lately seem to ignore during the .0 releases.
