Almost ALL Android Devices are "Abandoned" on the day you buy them;
Literally the only Android device I've got which got no updates is the Sony Xperia Play. I learned my lesson, and Sony can DIAF. (They explicitly promised ICS for it, but never delivered.) Every other device I've got has had at least two substantial upgrades, or will be getting them. TF201 got two. Moto G had one, is getting another. Nexus 4, not a problem. My crappy MK908 TV stick had two updates. All of these devices got at least a couple of years of support.
YOU brought up length-of-OFFICIAL-Support. you lose.
You don't even understand the argument, iFanboy. The argument is that once official support is over, your iDevice is garbage. At least there's a chance that someone will support your Android device. Now go throw your old Apple devices in the landfill and shut the fuck up.
