I dunno. Enthusiasts may track the versions coming out of Google HQ. But for most updating is a hassle rather than something they look forward to. This because it means downtime for their device, and if the update fails it may leave them with a bricked device (chance is small, but it is still in the back of their mind).
For most people a computer, a phone, or a tablet is an appliance.
