I'm looking forward to it. It's fast now because it's at least 4x more powerful than my old one (going by benchmarks), but I won't turn down 40% more. Especially if that translates to better battery life doing average CPU-light stuff.
I was of course careful to say had, and obviously this rested on the fact that lollipop was so universally shit for the ui.
Also, of you think about a ui getting faster, a fixed 200 percentage increase peer iteration, means the absolute speed increase gets relatively smaller as they approach zero.
