information about 'kindle'

i hope you could tell me is it easy to use and are the Electronic books easy to get and if it is better or worse than reading from a real book does it tire your eyes if you read on it a lot?

I would be so grateful if you could answer my questions

Once it's registered you download the books directly on to your kindle from 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.
