For various reasons, the Kindle is a lot of fun. Free books is part of it. Not only the classics but the freebies paying publishers sometimes give out to test the waters for the product they will soon put a price tag on.
Such as this popular old Indie scifi tale soon to be brought back as an Amazon Encore in paper. Meanwhile, the author is offering it free in various ebook formats (including the Kindle) at his website. Cool. You never see this in paper. Nobody could afford to do it.
