The physicality of a book is why so many people prefer the form factor of having thousands of books in a single, tiny, lightweight device they can keep in their purse/backpack.

I never again want to own bookshelves of books or have to track down a physical copy of an out-of-print book that I want to read.

Help one of your buddies move houses when they have thousands of books in bookshelves and tell me it's just publishers who have something to gain from e-books. :)

Btw, OP himself in the post even says that his Kindle has allowed him to "convert into a more fervent reader."
