I have that much pull? Haha!
Lag isn't the end of the world. It obviously annoys you to the point, that you have to question anyone posting they don't see lag. You want them to see your point of view and you just can't make them. That may be even more annoying than the lag itself, eh?
Relax man. Life is too short to stress over a little lag. Enjoy your nice expensive phone and more importantly, stop blaming everyone else for your experience.
It's like that little defect in your nice new car / boat / appliance, a TV that changes channels 1 or 2 at a time randomly, an air conditioner that won't display the correct temp 100% of the time, the ... These things should be right from the get go.
Stress? Blame? No. Just folks becoming more and more dissatisfied with what iOS is evolving into.
This is just a way that some can express this and at the same time potentially let others know they are not alone.
