Same here, especially since it'd mean it would /also/ run all the other open source operating systems. It'd be a great litmus-test ("hardware so open that even OpenBSD supports it").

Sign me up too!

But to be honest, the problem with Android is not the Linux kernel but the fact that most phones were never designed to be continuously updated.

Actually Linux is a very poor choice when a product depends on out of tree binary blobs to operate. The lack of stable driver ABIs and APIs are a real problem for long term maintenance. I'm really surprised that the BSDs aren't a much bigger player in the embedded space.

Wasn't the original Danger developed phones based on NetBSD?

Yes, but the real problem is the code source operating system that runs the cellular baseband.
