Previously requiring an invitation, subscription based e-book service Oyster has today gone live to all and brings a universal iPhone and iPad app to the App Store to make full use of it. If you read a lot of e-books, Oyster's $9.95 monthly subscription fee could be right up your street, with a library of over 100,000 books.
The app is free to download, and many of the books within the Oyster library are from HarperCollins, Houghton Mifflin Harcourt and all kinds of smaller publishers. The choice isn't going to come close to something like the Kindle store at this point, but for the price of a book a month you're opened up to as many pages as you can turn. Grab the iOS app from the App Store link below, or head on over to the Oyster homepage to sign up. The first month is free, so take a look and let us know what you think of it.
