Can I Borrow that Book? NO! Says Amazon

Amazon has crippled the Kindle ebook reading device with very restrictive DRM. They are going to have to do away with that, IMHO, before the Kindle will be able to take the world by storm, iPod-style, like I predicted when it was introduced. In promising news, the Kindle has been hacked to allow users to import non-Amazon content onto it. How long before someone hacks the Kindle to get purchased content off of it?
