There are attempts to get Android to run on non-Android phones. There are also attempts to run Ubuntu on mobile phones.

Useless. They only boot.

No Calling / Texting, not to mention sluggishness.

I hope nobody tries to actually get those devices to work fully. For fun, just to boot, yes. But by the time of anything decent coming out of it, a newer, faster, better phone is out there, and nobody really cares anymore about the old phone that was doing so much.
