As a leach, I don't like it. This could be the beginning of the end of cheap obsolete used textbooks. For years I've enjoyed going through bookstores, especially in college towns, just to pick up interesting looking textbooks dirt cheap.
One has to wonder how much longer the typical bookstore (in it's current form factor) will be around. The large book retailers are already retrenching, but hopefully a market still exists for the small, independent, bookstores that add so much character to Main Street.
