We have no books any more (apart from kids ones).
I used to have an entire wall full plus boxes in the loft (started out alphabetical, but then I had a crazy weekend where I arranged them in a rainbow, and never looked back. I knew it had gone too far when I started selecting my next reading book by the colour of its spine though!), but now I have about a thousand on an ebook (mostly antique science fiction), and more on my phone (newer, purchased stuff), and more on my computer, and I I'm in computing, so most of my reference books are out of date after a few years, so they are gone too...
People coming to my house would get the wrong idea entirely - I read every night, and spare moments on the train, I always have at least one fiction book on the go, plus goodness knows how many reference articles and manuals I read - just none of them are in print. It's a bit sad, but I do love my ereader.
