I'm waiting for the day my Linux browser agent string pays off. So far, I've only seen random sites refusing to work for no good reason.

I wonder if Linux users spend more or less. I can definitely imagine that American Linux users are wealthier than Americans in general if you exclude non-traditional distributions (Chrome OS, Android, etc.) from the Linux category.

In the beginning of Humble Bundle (pay want you want for a collections of games for all platforms) they showed the average price paid per platform. Linux was always the highest.

I doubt this had little to do with any relationship between linux users and their likelihood of overpaying on a hotel room or rental car.

The price paid by Linux users was almost certainly bumped up by Linux gamers explicitly trying to support game studios who supported Linux.

You wouldn't see the same thing with hotel rooms or most other products that weren't intimately tied to the OS itself.

Yeah, there was (or is) a inverse correlation between how common an OS is on the desktop (Windows, Mac OS, GNU/Linux; starting with the most common OS) and the amount people are willing to pay for a HumbleIndieBundle release.

This is presumably partly because customers appreciate that game studios see their chosen OS as a viable release target.

Skew wealthier, but are more practical with that wealth. Cuts both ways, the more expensive room will have to be perceived as a better value regardless.

Take that idea in the other direction. Vendor tie-in with browser maker to grant users a decent discount for use of IE or even the new and allegedly compromised Opera? I'll give it a shot on your site.
