> One Chinese participant had heard from a friend that, for the same product, Taobao charged iPhone users more than it charged Android users.<p>Interesting. I recall reading that some online flight booking site did this for Mac users a few years ago, along with raising prices if you search for flights and then come back a few days later. I always make a point to use a VPN and spoof my browser ID when I book travel just in case.<p>ETA: Ah, as I continue to read I see the article references this as well. No idea if it's true, but I'll continue my behavior. I suspect that people <i>do</i> see prices change, but that those changes are based on other variables.
