No I've been boxing up and storing them in my parents basement, or donating, the vast majority of books I've bought for years anyway. I seldom re-read, and a move a lot and hate dealing with lugging boxes of books around.
So the main reason I bought an eReader was to not have to buy real books anymore. Other than academic books and those I keep in the office and they get moved by hired movers if I have to switch offices or move to a different university etc.
But ideally when I move again this summer I won't even have a bookshelf at home. Just my kindle with all my real books on the shelves in my office.
