This fragmentation issue is always presented when a flaw like this is incorrectly attributed to Google, but somehow that has nothing to do with Android? That seems like a silly thing to say. Yes, iOS suffers some problems but so does Android, as a fragmented beast that is still stuck on jelly bean as the majority version (which IMO is pretty lacking). I do look forward to Android's future though.
I don't think anyone is suggesting that we explain anything to regular consumers in Verizon stores. The point is that an HN member should be able to understand and appreciate the fact that stock Android is very different from what most Android phones have, and that those who want stock Android should get a Nexus.
