440:, Princeton University Press: 1950) disappointingly seem to propagate the misconception that associated bundles are some kind of mysterious concept. Now I may have missed some particular subtlety, but my understanding is that (using Steenrod's nomenclature) two bundles are associated if and only if they are associates of the same principal bundle. So I find the very idea of "associated bundles" to be a bit of a non sequitur. I don't mean to say that the article shouldn't exist, but I do believe that it can be clarified extensively. I moved a few of the vague sections into the talk page for now.

I can see how this definition through "subterfuge" can be more easily understood by someone who isn't yet comfortable with principal bundles. I'll do my best to preserve the spirit, if not the actual letter, of the article. Thanks for sorting me out,

I, for one, find the principal bundle picture more intuitive. (Of course, I've been working with them for some time, so I am indeed already biased.) Perhaps we should compromise. The idea behind associated bundles is just that they have the same structure group and "the same" transition functions

I admit that I'm not all that familiar with the most general definition of an associated bundle. But in common parlance among my circles, an associated bundle is simply a bundle associated to a principal bundle by means of a
