If you are an affiliate, it comes in handy to use rel="nofollow" on all affiliation URLs. If every affiliate links to a website, lets say for an ebook, then you're in fact helping the actual website to get a higher page rank in Google.
Because if 1000 affiliates link to this ebook website, Google will count those links and think it's an important website.
So what happens when the original website hits page one at the top of Google? Then your affiliate website will be on page 3 or 5 or even somewhere on page 300.
In the end your giving the ebook a boost in google, and you won't be making a dime. So if you use rel="nofollow", you won't be helping the ebook website to the top, but rather your own website.
Hope you understand the above, if not, ask me.

thats a really good way to put it. I never thought of it like that.
