Greetings all! Please could someone explain the lag / choppiness on the retina ipad ios 8.0 + 8.0.2 + and now 8.1 when using chrome / facebook / safari / etc? My retina mini had no issues on ios 7.1.2. Do you believe this issue will be rectified going forward? Most annoying since 7.1.2 rollback not possible! Many thanks!
