I've come to prefer them over paper books for pure convenience, even though I still buy books because I like books,
I tend to go the other way. I prefer the paper and given the way the market is, ebooks have a habit of disappearing or changing formats. I want my reading material to be mine, not some profit based company that's renting me the book for only as long as they are in business.
I note from the article that hard copy sales are up but the ebooks business is what's killing them. It makes me think that there's a lot of folks who feel the way I do...
