information about 'kindle'

i hope tu could tell me is it easy to use and are the Electronic libros easy to get and if it is better o worse than lectura from a real book does it tire your eyes if tu read on it a lot?

I would be so grateful if tu could answer my preguntas

Once it's registered tu download the libros directly on to your kindle from amazonas, amazon it's really easy. I can't speak for anyone else but I do occasionally miss the feel and smell, but the reason I got one in the first place was because I had literally nowhere left to store books, I've never had any problems with my eyes concerning my kindle.
