I started in 2007 because I am a gadget person next to being a book lover. I love the thrill of cruzing the shelves for the same reasons of that spine, cover or what I know about the book. I've worked in bookstores for a 1/4 of my life. I live eat and breathe them.
The one advantage that stands out the most is I discovered with my ereader is the ease of carrying that large book I'm reading that I would not carry everywhere to read it. The convience of having it in my pocket makes me read more when I have a moment in time; at the bus stop, in the coffee line or on a break at work.
Sometimes when I am back at home I will pull out the hardcover edition and pick up where I let off with the ereader. I dont think I can let go of books, but I have also embraced the ereader for its convenience.
