E-readers are usually designed to only offer access to the online shop of one provider. This structure is referred to as (digital) ecosystem and helps smaller companies (e.g. Kibano Digireader) to compete against multinational companies (like Amazon, Apple, etc.). On the other hand, customers only have the possibility of purchasing books from a limited selection of ebooks in the online shop (accessible via the e-reader) and therefore do not have the possibility of purchasing e-books from the open market. Because of the use of ecosystems, companies are not forced to compete against each other and therefore the cost of e-books do not decrease. With only the option of using an online shop, the social interaction of buying or borrowing a book disappears.
