Variations on Normal posted the iBookend concept, jokingly saying "for those who can't find a use for the iPad."
Strangely enough, however, the iBookend intrigues us and makes us want to purchase it. But alas, it's not a real product. We would love to see this creative idea come to life, as our iPads would fit in nicely with our vast collection of books. After all, what's cooler than an iPad stand that doubles as a bookend? Frankly, we're surprised Apple didn't come out with this idea and sell the product for $99.
