My guess is the convenience of having Linux pre-installed instead of having to go through a new installation yourself? I don't own either, so I wouldn't know for sure, but I think it's somewhat valid that not every high level developer nowadays want to deal with installing Linux OSes. Having Ubuntu preinstalled is welcoming for a lot of the dev userbase who comes from a Macbook world expecting things to be plug and play.
