Android upgrades are a contentious topic. Bring 'em up in any way, and you're bound to see some riled up people. I should know: I've observed and analyzed Android upgrades for years now -- all the way back to the now-ancient-seeming Android 2.2 Froyo era, when widespread rollouts for the platform were still an untested concept. And in all of that time, one thing has stayed pretty much the same: By and large, Android manufacturers suck at delivering timely and reliable OS updates.
But hang on: Not everything about the Android upgrade situation has remained constant over these past several years. In fact, one very significant area has evolved considerably -- and it's an area that's almost always overlooked as part of the Android upgrade discussion, particularly when iOS comparisons come into the picture.
