Kindle, Zune DRM Restrictions Coming Into Focus

t's not news that the media you buy for both Kindle and Zune are protected by DRM. Readers are sending in stories of some of the ramifications of that fact. First, Absentminded-Artist notes an account at Gear Diary recounting what an Amazon rep told one user about download limits on Kindle books.
"One facet of the Kindle's DRM has reared an ugly head: download limitations. Upgraded your iPhone recently? Bought a new Kindle? You may not be able to reload your entire library. There's an unadvertised flag: 'You mean when you go to buy the book it doesn't say "this book can be downloaded this number of times" even though that limitation is there?' To which [the rep] replied, 'No, I'm very sorry it doesn't.'"
Next, reader Rjak writes
"DRM is a bad idea, poorly implemented. One of the many many valid reasons to drop Zune and it's marketplace is the DRM validation error you see below. The vast majority of the music I had purchased last year is completely gone. There's no refund, the music doesn't exist on the service anymore, the files are just garbage now. Here's the error (screen capture): 'This item is no longer available at Zune Marketplace. Because of this, you can no longer play it or sync it with your Zune. There might be another iteration of it available in Zune Marketplace.
