No, it's really not. A base model Nook can hold about 2000 books. If you have the older simple touch with an SD slot, you can expand that into the realm of....far more books than you'll ever live to read, quite frankly.

To clarify: I meant the implied use case (of holding thousands of books), not to the fact that modern devices can easily store that many.
