As much as I'd love for it to be viable, it seems thats a far ways away. Linux suffers from battery life issues and if you need to run android apps I've heard its not a pleasant experience.

I can't say because I have yet to get to a point where my current phone is beyond repair, but there's gotta be one person who can give some solid advice.

However, what I do know is that there are no damaging software updates and you have a lot more control over your phone.
