I started migrating to ebooks before it became a physical necessity, but since I was never particularly in love with the physicality of books, leaving them behind was no wrench. I do read on my PC quite a bit, it's what I use for PDFs and anything color-rich. Other than that, my Kobo wins hands down. I'm 80% through the Delphi Classics Maurice LeBlanc collection, and I shudder to think of how heavy, awkward and unwieldy a 4800 page book would be. There are some rare cases in which I prefer dead tree, mostly books as art -my
Discworld Atlas, the bilingual, quadscriptal
Dialogs of Pyaasa. There's also my collection of Hindi-Urdu dictionaries (though if they were digitised, I'd ditch the paper stat), but in the main, I consider that I've lost very little by going digital. If I crave a shot of vanillin to the nose, I can always wander through a secondhand bookstore and inhale deeply.
