I love, love, love my Kindle.  I have a leather cover for it, which gives me the feel of a quality book, but the readability in the bright sunlight that I'm loving with the Kindle.  For Christmas I got a Kindle Fire, which I also love, but for me it serves a different function.   The Kindle is nothing but a reader for me (though you can surf the net on it, it is more cumbersome), and I only turn the WiFi on when I need to go buy a new book or download ones that I've already purchased.  My Kindle Fire is my tablet, my internet connection without the bulky laptop or PC.  This allows me to be on FB, or playing games, while sitting in my living room recliner with hubby while he watches TV.  I do read on it, but it is more like reading on the PC, so I prefer the regular Kindle for my reading.  I love the fact that my smart phone has the Kindle app, my laptop has the Kindle app, as does the PC, so no matter what I have with me, or where I'm at, my books are always available and they synch between the devices so I can pick up where I left off, no matter which device I'm using.

I have pretty much given up on reading actual paper copy anymore, as I like the portability of the Kindle.  It takes up a lot less space when traveling than regular books, especially if you were to pack more than 1, like I normally have to.  I agree with the previous poster who stated that the typos on some of the e-books is abhorrent and drives me nuts, but I'm finding that if I move from the cheap or free books and on to my preferred authors, some of this has improved.  I really feel that e-books are coming into their own, and so the formatting and editing will improve on them too.  I do like that the Kindle quickly allows you to change the size of the font on the book, as each book appears to have it's own font, and what is readable in one book may be unmanagable in another, so this smooth transition to a different font helps alot.
