Dana Mattiolo for the Wall Street Journal:

Orbitz Worldwide Inc. has found that people who use Apple Inc.’s Mac computers spend as much as 30% more a night on hotels, so the online travel agency is starting to show them different, and sometimes costlier, travel options than Windows visitors see.

Orbitz says that users can overcome the issue by ranking results by price. If this leaves as nasty a taste in your mouth as it does in mine, though, the better solution might be to skip Orbitz all together in favor of a different site that doesn’t discriminate based on your platform. (The article suggests that Expedia, Priceline and Travelocity do not, by the way.)
