I think pretty much all music on itunes is drm-free these days, yeah. And much, much better sound quality than the original itunes.
My first ipad Trek ebook: Trek Fail! by SNW contributor Robert Jeschonek. He's done a few ebooks with Trek connections. This one's a look at his various Trek pitches and fiction, analyzing what made them work or fail. It'd be interesting to see something like this from someone who's had more stuff actually published, but that kind of writer is probably busy enough already.
