Wow. You're so smart. You know what I did own that ran iOS 8? An iPhone 6. Next time, how about you try to understand what people are saying before spewing out insults. Oh, and performance has improved on the Air 2? Try rotating in the Spotlight pulldown. Great performance there...
This is all very subjective. My tolerance for lag is different from yours and so is my perception of fluidity and speed than others.
So arguing with one another is silly!
If someone feels it is still laggy, then it is laggy for them. Why try to convince them it is not just because you don't think it is?
Just downloaded the beta and I can see visibly no difference on my iPhone 6 and Air 2.Control Centre still stutters and I am now starting to doubt if it it will ever get fixed.Spotlight pulldown still has that split second freeze.Mobile data Menu still stutters while scrolling down the list of apps.Scrolling in apps still has this stutter like I am in Android Gingerbread era.
All in all,a pretty lacklustre update.
Reported for name calling.
Every new beta comes out and I'm delighted with joy that you guys haven't had your lag fixed once more. Apple is doing a great job. I love it.
