I was one of the ones that updated to iOS 8 and quickly reverted back to 7.1.2 while it was still posssible after finding decreased performance on my iPad 4 Retina. Stuttering, cars showing up all black, overall sluggishness some apps not working at all... 

I know several of you made the same 'mistake' and got stuck with it. Have you tried iOS 8.1 yet? Any improvements? Is it any better than iOS 7.1.2?

Oh, and of course... is the DeLorean and Kotter still around?
