That's funny: I worked with Byron Preiss back in the day (my company did two CD-ROMs for him), years before he sadly passed away in an auto accident. A bit of history: Preiss did a great deal of book packaging relating to comic books and science fiction. In the 80s he tried to do books on floppy discs, but his big break came in the 90s when he launched a CD-ROM company that went public. The company didn't do too well, but that was more of a reflection of the CD-ROM market than Byron. After the failure of that company I recall that Byron tried to do e-books again, but it didn't quite work. The problem wasn't his content, but the fact that the technology wasn't quite there yet. If he were alive I'm sure he'd be creating interactive books for the iPad.
