Sorry but lollipop simply isn't a consistent experience across devices.
Runs like a dream on my N4, runs like a 3 legged dog with congenital syphillis on my N7(2012), graphically great on my N10 but the wireless on that device no longer does more than 60kb/s making it useless since it's primary function used to be for streaming media.
Just because there are negative reports about an android update doesn't mean apple fanboys are trolling. There are some very real problems with this release that google needs to address.
