agree with one of the comments
gingerbread = android version of windows xp
Android millions phone and millions tab with different hardware.That's why i still prefer Iphone and Nexus don't get me wrong i do like the S4, HTC and Sony but when it comes to update still Nexus the winner cause Google IPHONE.
if real world usage is taken into consideration, the rate of adoption in cm10.1 is high
Looks like Anndroid's Jelly Bean dominance is not in it's good days (according to the charts and surveys). GS4, may have a chance to rocket the shares of JB versions or may be, the down fall of Android would start. Who know, but hey, no one knows the future right? So just wait and see what's next.
So, If there were 700 million android now.
times 2% = 14 million
Google has sold 14 million nexus 4
New Devices are coming with jb thats why it share will keep increasing until new vers comesout but gb isnt going anywhere soon noone wants to replace old devices and companies dont wana update phone so peops can buy new device :P lets see how much time this things goes
