I forgot to address this earlier... I suppose it all depends on what you want to read. I went fictionwise and I found more Science Fiction Books that were readable under ereader (secure or multiformat) than I found on mobipocket's site. So I think for practical purposes, there is probably plenty to read for anyone.
