I have carpal tunnel syndrome...some books are heavy...or awkward to hold
With a kindle I just move a finger to turn the page..I don't have to adjust the book, binding, use a bookmark, dogear a page, remember my page. I love it. Also I have collected thousands of books over the years. Rarely will I read one more than once. I hate dust. Books draw dust. Now i just keep a few collections on my shelves and I don't worry that I have dust collecting to bother my allergies.
You can sample a chapter before you buy at Amazon.com. And my books I order are on my kindle in seconds. I will always have a book. And many books are free..and soon I will hook up with my local library, haven't done that yet. A few times in life i used the library, but I didn't like waiting on a list for a book. Some people need alcohol, I want my book. It is not very high tech at all. I am not a geek...it is so simple to use.
