Kindle books, according to Mashable, are outselling hardcovers. Over the last three months there was a 30% margin and in the last month there was a 44% margin. Granted, these numbers are skewed since Amazon doesn’t reveal all of its data (i.e. how many books were actually sold) nor does it compare to how many paperback books were sold.

The article, however, did get me thinking about why ebook sales might be on the rise. One thing that comes to mind is the intangible nature of the ebook. With a traditional hardcover, or even paperback, the customer will need to pick it up, hold it in her hands, sniff at it a little bit, figure out where she’s going to put it, and then flip it over to see the heart-stopping amount of money she’ll need to dish out for it.

On the flip side, ebooks are ephemeral. There’s no need to make room for it and it’s (usually) much cheaper than the hardcover equivalent. For the price of one hardcover, you can grab two ebooks (assuming that it’s not a bestseller or renowned author). Plus, it’s easy.

With the click of a couple buttons, sometimes only one, you have a new book waiting to be read. It’s so easy to be caught up in the whirlwind of buying that you don’t realize how many books you’ve just bought…and it all goes back to ebooks having an ephemeral quality. With physical books, you can look at the stacks and say to yourself, I think I’ve picked up too many books, but with ebooks, you don’t have that. Or am I wrong?

I’m curious, if you’re an ebook reader, why? Do you appreciate the books taking up less space? Do you appreciate the blazing speed at which you can have the book and start reading? Is it something else altogether?
