None of those advantages have changed, but I've recently reached a position where the possibility of having bookshelves again is more viable, and I've been thinking about what kinds of books would be on those shelves. Mostly, my physical book collection consists of nonfiction tomes, and books from my childhood. Contemplating this, I've been thinking how nice it would be to have some of the books that I've read on Kindle, the ones I've really enjoyed or reference/re-read very frequently, as "real" books. Yet buying duplicate books seems terribly inefficient.
Though I've read Timothy Zahn before, and enjoyed his books, this wasn't a book that I sought ought to read. In fact, it wasn't even on my extensive reading list. After finishing Back to Methuselah, nothing on my reading list was really calling out to me to be read, and I happened to see that this piece was in Prime reading on Kindle, which meant I could read it for free. A short, free, light read seemed the perfect thing coming off of a heavier piece like Back to Methuselah, while trying to think of what I actually wanted to read next.
