I went back and found every Android phone shipped in the United States up through the middle of last year. I then tracked down every update that was released for each device – be it a major OS upgrade or a minor support patch – as well as prices and release & discontinuation dates. I compared these dates & versions to the currently shipping version of Android at the time. The resulting picture isn’t pretty – well, not for Android users:
Wow. That’s all I got for that one.
