There is something really special about a 1-hour loan period for a digital book, and I'm grateful to IA for letting me experience it.<p>Personally if I'm interested in a book, especially if it's on sale, I prefer to add it to a short-term wish list and then put it away for a while, giving some time to consider whether it's more of a passing interest, a possible new interest, or more of a core interest and worth considering because its content will likely help improve my fundamental energy levels in some way, or something like that.<p>Some book services make this process of mine a total PITA. Like with Google Play Books, I really like the responsiveness of the their app compared to the Kindle app, but sometimes you put a book that's on sale on your wish list so you can check it out later, only to find that the price immediately reverts to pre-sale. It's hard to not see that as a predatory pricing change, bug or no.<p>Switching over to IA, the one-hour loan really helps me figure out WTF I'm liking/disliking in a safer, less-mercantile context (:-)) and a lot of the time what's needed here subjectively is more like a dip into an unfamiliar world for a few minutes, nothing worth spending money on.<p>To me this is a massive improvement over more typical sampling models like the first-chapter-sample which a lot of the time is more like a waste. In a physical bookstore I always got a lot more buying-impetus if I could just skim the entire thing, and again about an hour was all I'd need for that.<p>So this has been really cool to experience, just as a me-sized data point, and a good reminder to donate to IA.
