Query: You do not own any book you buy for Kindle! Boycott tethered media!

The terms of service gives Amazon, NOT YOU, the ownership of the books on your Kindle. Do not support "tethered media," especially under the terms Amazon mandates. They have removed George Orwell and Ayn Rand books from people who have purchased them, it's like if you went to Border's and bought a book, then later, claiming copyright issues, employees from Border's came into your house and took the book back.Do not buy tethered media for any device. Companies can go into your computer and remove data whenever they want under the terms of service tethered media requires. If I buy a book, I want to own the book... now it's like paying $10 to rent a book from your library, not a great deal. You are only leasing your e-books, and they can take them back whenever they choose (and they have).The Kindle hardware is adequate, but the terms of service should be a deal-killer for anyone paying attention.
