Kindle

Thought of buying a Kindle from Amazon?

...the Kindle locks you down with more rules than the Army Field Manual. The Kindle won't let you resell or share your books. Anything you buy through the reader is fixed to your Amazon account, readable only on the Kindle or other devices that Amazon may one day deem appropriate. (The company has hinted that it'll build an iPhone app that can read Kindle books.) Even worse, you can buy books for your Kindle only from Amazon's store. Indeed, the device makes it difficult to read anything that's not somehow routed through Amazon first—you can surf the Web on the Kindle, and you can convert some of your personal Microsoft Word or text files to the device's format, but doing so is slow and not very reliable. In order to read blogs, magazines, newspapers, and books, you've really got to go through Amazon's store first.

Don't.
