Ubuntu (looking into Mint)

After having perfectly good documents/programs/hardware getting obsoleted by Microsoft, Apple and other private entities through the years. I switched to OSS, Took years to get proficient again but I have a lot less worry that one day X is just not going to work anymore.

If you can get some adequately advanced one that exists only as firmware that will be static for the rest of my life, that would be a compelling reason for me and a lot of other developers to switch - or at least adopt as a serious platform for development.
