Kindle Paperweight is one of my favourite gadgets ever. If you like to read when you're about, its much more convenient to carry than a book. Its easier to hold than a book(something people don't talk about much, but is a great positive). I can read in darkness or low-light settings just fine. I can read multiple books without having to handle them all individually. I can adjust the font, spacing and font size of what I read. No licking fingers or fumbling to turn pages, you can do it all super easy, with just one hand. You never have to worry about wear on your books when re-reading your favourite books for the 5th time. Prices for e-books are almost always a fair bit lower than normal books. This is especially nice when a book first comes out in hardcover only, which tend to be pricey - no such issue with e-books.
I could probably think of a few other good things about it. But basically, while there is definitely something nice about reading a real book, the advantages of having my Paperwhite outweigh this massively. In the end, I find I read quite a bit more now and I know I'm not alone in that, which is probably the best thing you could say about it.
