This document discusses the advantages and disadvantages of e-books compared to printed books. E-books allow users to purchase any book digitally and access it across devices. They are portable, searchable, can be read in low light or darkness, and are more environmentally friendly than printed books. However, e-books also have limitations like requiring compatible hardware/software and risk of data loss. While e-book sales are currently higher than printed books due to lower prices, both formats have their place and e-books will not completely replace printed books as people value aspects of each.
