I also asked about Android, which you completely neglected to answer. There's been heaps of devices from manufacturers that shipped with obsolete software, with upgrades never announced nor delivered.
How many of those are still in use? How's the battery holding up on 3 year old devices after daily charge cycles?
Nope, I did. Even those phone with android 2.3.x can do most of things that 4.1.x can, including NFC and stuff. You're mixing up feature with function. Battery? My N9 need to be daily charged, So does my Onyx 9700. I can get it to last for 2 days if I stick it to edge, but what smartphone uses edge? Even cheaply made chinese androids can get H+. Not much of a difference really
