I wanted to buy another e reader that is universal and will work with any website and download any e book on any website(except Amazon cuz only the Kindle works with them.)I also called Sony and u can only download on there website and not any other websites.Is than an E reader that can be used with any website?

I am considering getting a Kindle. I read somewhere that there is a limited # of times an e book can be read on a single device. This is to discourage people from sharing books. Any truth to this? I know they can only be downloaded a certain # of times.
