With the Humble Games Bundles, people reasoned that Linux users might be paying more because they were so happy to get games that run on Linux. The Humble Music Bundle indicates that there is more to it than just supply and demand. I would guess that a significant percentage of Linux users that buy the Humble Bundles are developers/scientists. These groups create content themselves and therefore they might value content (and especially DRM-free content) higher than other groups. It might be really interesting if the Humble Bundlers collected some basic demographics.
