This is very good progress. KitKat is actually more optimized for lower end hardware so there should be less of a reason to hold off on upgrading older models.
The fact is that OS version fragmentation is starting to be less meaningful as Google is transferring a lot of core features over to Play Services, the Google Experience launcher, and other stand alone apps. I already have most of the Kit Kat features shown on the Nexus 5 on my GS3 thanks to this. Brilliant work around to overcoming carrier related "testing" and slow manufacturers.
More complete of an OS? If you're going to say things like that, at least have a clue as to what you're talking about.
Sure Android has a lot of market share, but that doesn't make it a better option. With a plethora of different handsets and tablets running Android (vs a few devices for Apple) this SHOULD be the norm. Android devices have more choice when it comes to size, etc, and the general public has the mentality of bigger is better. I cringe anymore when having to look at problems on my wife's Galaxy S4. Massive battery drain all of a sudden, and the battery meter is useless in trying to determine where it went because it's consumed by "Android OS". Now, the user is either given the option of googling and tracking down the apps that have gone wrong, resetting the device to factory defaults or just dealing with it.
I used Android for years and for me the pros are no longer outweighing the cons, which is why I switched to an iPhone and prefer the experience. I get updates at the same time as everyone else and I know I will get them for right around two years per device. Rather than have to worry if Samsung or HTC or whoever is going to pony up the effort to release a good update, or even one at all.
Your post is entirely void of ANY facts. None! Just a random anecdote which i believe must be false. galaxy phones rate higher than iphones on almost any tech site except for those run by apple. galaxy phones also have TWICE the talk time of an iphone. now run along and stick with your crippled glorified app launcher
