Sure, it's a lot of little things. A couple of examples: Hangouts you cannot send multiple pictures in a MMS, you have to send them one at a time. Another example: Google now is not a great personal assistant, if I "call Mario" half the time it does an internet search for Super Mario bros. Another example: Bluetooth function, google now chime is extremely loud, louder than system volume. Another example: Google can polish Google Voice, or fully integrate it into Hangouts, either way make a decision and finish the product. Another example: If Google now isn't meant as a personal assistant, Google should invent their own personal assistant to compete with Cortana and Siri. Another example: How about working on a dark theme? Another example: How about working on Android backups? What about having multi screen mode? One handed mode? Etc. These are all more valuable to me than cosmetic changes that IMO were not needed and a waste of resources.
I can list out many more, but my point was that these are bugs and functionalities that bother in my day to day use. Whether they are show stopping is up to the user though, for some they may not be a big deal at all. Additionally I find the cosmetic changes in Lollipop not only useless, but actually detrimental to using my phone in the dark, once again my personal opinion. Which all ties into my original statement that in my opinion Google should use their energy not for cosmetic changes, but to fix bugs and increase functionality.
As for juvenile, it's not ironic in the least. When someone comes in and rudely proclaims my opinion is "garbage", "nonsense" and that as an Android user myself I'm "engulfed in Apple" I can't find a word other than juvenile to describe that. Sure I'm up for a nice discussion about differing viewpoints, but not when someone comes in with that fandroid attitude. You should not take offense at any criticism of Google and immediately call criticizers Apple fan boys because of that criticism. THAT is irony.
