I have the cheap $79 Kindle. It is supposed to have commercials, but I do not have Wifi, I have dial-up for my internet service. So they cannot put the commercials on my Kindle. I did not know that until I received it.
First I would like to say, I love having a hard copy of a book. The smell of ink and paper, weight of the book, the feel of holding it in your hands is all a part of the experience in the joy of reading. But there are some books I like that I cannot get in print, but you can get it in ebook form. Plus the mass paperback book is all but dead as more and more publishers abandon the medium for ebooks. The reason being is that the ereaders have taken the place of the mass paperbacks.
I know that was more than you asked for, sorry. I love my Kindle. I presently have 105 books on it. I love old pulp fiction from the 30's and 40's, especially science fiction. I cannot find that stuff in paper form. Plus there are no book stores in my area. There is one used book store but it mostly carries romance novels, not my thing. I would have to drive to another state from my area in order to find a book store, or order on-line. But having my Kindle has made it so easy to find something, download it to my computer then drag and drop onto the Kindle. Maybe too easy.
Having my Kindle has caused me to read a lot more than I normally do. Since Christmas I have read 6 books in my spare time. It is so easy to pick it up and flip it on, read, flip it off. You go through a book in no time at all. Yes I do recommend one if you love to read and don't mind not having a tangible copy of a book. You can keep a whole library with you whereever you go.
