Everything else was/is indeed destined to move to its digital form sooner or later no matter how much the physical good producer regrets it; but you cannot take it away from physical books. Ebooks are handy. They are portable, safe from wear and tear, cheap and what not. But what about those moments when you really need to take your eyes away off the screen but still want to be productive or have some quality time reading.
This might be just a personal POV, but over the time looking at screen becomes so usual that you need an extra physical thing to get that kick. In my case it's physical books.
