I hate knowing that I own one of the highest end and best selling devices and I literally have zero date or knowledge of whether or not I'm getting 4.2. Even the hacker community hasn't released decent 4.2 roms for me (that support my hardware like s-pen, etc).
Apple does updates right.
It's Samsung, HTC, etc. who are doing updates wrong (though carriers may have some part in that).
Edit: I should say Google is getting better with updates. I'm still a bit disappointed with how they handled the Nexus S update to 4.0.
I know one will argue it's not a viable solution for the 99% of Android phone owners out there, but the modding community for Android is very quick to update most flagship phones on most carriers, and even develops on phones that carriers have stopped pushing updates for. My Galaxy S1 had Ice Cream Sandwich on it when I finally traded up to a Nexus 4. It's not as convenient as Apple releasing the official update and rooting+customrecovery+clockworkmod+customrom is a process complicated enough to bar many people from entry, but for those capable folks, we can get updates almost as quickly as those on the Google flagship phone-of-the-day.
The N4 is lacking LTE. Maybe not a dealbreaker for some, but it is for me.
I guess I'm paying for the features I wanted with a currency made of "waiting for updates".
6.1.2 was 12.8MB: http://images.techhive.com/images/article/2013/02/ios612-100...
