Oh yeah. I have found some books that way and then checked out related items for more. But it's not very efficent at all. If I knew a boatload of spanish books I want to read then I could search for 'em, but I don't. That's why it would be super handy to just get into some spanish category/setting and just be able to browse through lots of spanish books. Because there got to be lots of spanish books there right?
Amazon has just opened a spanish section of it's kindle store. There have a large selection of spanish books, which you can use with the kindle app for the ipad, of course. They have a few novels for free.
