I just stumbled over the data for the sales of the Humble Indie Bundle. The money made as of Saturday 09. May around 6pm local time is: $612,300 by 72,969 people with an average price for the bundle of $8.39. The average amount by Linux users is $13.95. That is more than $6 more than the average the Windows users spend.
The revenue per operating system is: Windows: 52%, Mac 24% and Linux 24%.
With a market share of Linux operating systems of only 1% (Source: Wikipedia) I am wondering, why they make 24% of the revenue for the Humble Indie Bundle.
Are there so few good Linux games, that the personal value is much more than for the spoiled Windows users?
Are the main Linux users all people with good jobs and can just afford to pay more?
Are the Linux users more likely adults than kids (as on Windows) and therefore have more money?
Do Linux users safe so much money on other software, that they have it for games?
Any other ideas? Or a solution perhaps? Please tell me.
