Only when there's a library nearby. Otherwise it gets kinda expensive, which is another reason I love Baen Publishing. Not only do they have CDs in some of their books that have older books on them in various formats (Rich Text, HTML, etc...), but they have these same books online in the Baen Free Library. Recall the arguments about the RIAA's poor system of dealing with P2P and online filesharing, when I agreed with the school of thought that says their methods are positively Neolithic? Baen Publishing is a good example of a possible right idea, that free offers are perfect hooks, especially for merchandise where hard copies are so superior to the digital copies.
