My wife and I sat cross-legged on the floor of a local Barnes & Noble store recently, surrounded by several large piles of books. We were searching for interior design ideas for a new home that we are planning to buy.As we lobbed the books back and forth, sharing kitchen layouts and hardwood floor textures, we snapped a dozen pictures of book pages with our iPhones. We wanted to share them later with our contractor.
