What aspect of the experience are you tired with? It's just that I upgraded from a GNexus to a Nexus 4 about three weeks ago (I know, I'm pretty behind the times) and it "refreshed" my feelings for Andoid a bit. My GNexus was starting to annoy me, bugging out on Maps, navigation etc, but the Nexus 4 is a far smoother experience.
I admit, the text size thing is my biggest problem with Android (Chrome) at the moment.
The constant freezing, apps force closing, the constant taking an age to load the app drawer for no apparent reason. I don't have that many apps/widgets running.
It just feels sluggish to use. I hate it with a passion.
