So here's a novel idea: when a device reaches its end of life, manufacturers should provide users with a way to keep the flame burning. In a nutshell, that's what Lenovo has done with the Ideapad K1.
Here's the gist: the company is finished with this device. They no longer sell it, and it's clear that, past the most recent update (Android 3.2), they no longer plan to support it. So, they made a smart move: they built stock, unmodified Ice Cream Sandwich for the the K1, and released it to the public.
