I'd honestly rather read linear (read from page one to the end, one page at a time) fiction from it than a book, because I can't always get comfortable with a book. Hardcovers are sometimes a bit heavy, and paperbacks don't always lie open easily. The Kindle is incredibly light and thin. I can hold it in one hand easily. The page turn buttons are conveniently located. Page-turns aren't instant, but they're probably quicker than turning a physical page in a printed book (there are just a lot more page-turns unless you choose a small font). The contrast is better than other ereaders I've seen. There is zero eye strain in good light. My eyesight isn't the greatest and I like being able to increase the font size and read without glasses. I love being able to browse the Kindle store and read samples before deciding to purchase. The "experimental" browser is surprisingly usable, but isn't great. It is useful for browsing wikipedia and blogs. The biggest drawback to the browser is the awkward pointer navigation, using the 5-way pad. It syncs your furthest read page over the internet so you can pick up where you left off using your iPhone or iPad.  Kindle 3G Wireless Reading Device, Free 3G + Wi-Fi, 3G Works Globally, Graphite, 6" Display with New E Ink Pearl Technology
