but I've already bought it?

Those who want to buy music legally (based on the current payment model) may have been wrestling with the issue of having to re-purchase the same content on a different format. The same applies for many entertainment formats - the shifts from vinyl to cassette, cassette to CD, CD to MD (okay, maybe not), but certainly from VHS to DVD.

It seems a bit wrong to expect people to pay for exactly the same material on a different format.

When I read this post by Tom Peters, I was reminded of the issue. Here's the intro:

Everywhere he goes, Cool Friend Dan Ariely, the behavioral economist, meets people desperate to understand what is going on with the economy and why we were blindsided. In response to this demand he has updated his book Predictably Irrational. On the shelves May 19—today!—you will find Predictably Irrational, Revised and Expanded Edition: The Hidden Forces That Shape Our Decisions.

It seems that the it's okay to charge because there's 25% more insight in the book, but to my mind, it's pretty simple. I bought the book. I don't need to get another copy of the content I've already got! I have a receipt (it was bought from Amazon), so Dear Dan Ariely (or at least your publishers) can you give me access to the new content as a PDF, please - even for a few pounds?

What are the chances?
