Ebooks have huge advantages compared to physical books. They're availble everywhere (no need for long errands/waiting just to find the book you seek), much cheaper, searchable and don't take up space in your home. They're not lendable (yet), but that's the only issue with them.
I'm not saying that ebooks are "the correct choice". A lot of people still love the feeling of physical books, perhaps rightly so. But please don't tell me that buying ebooks are somehow wrong or any lesser than buying physical books.
