While not exactly books per se, magazines can be inspiring as well. Along with availability of inexpensive hardware, I suspect that electronics and computing enthusiast magazines were one of the catalysts for computing becoming a popular hobby in the 1970s and 1980s.
Although we may not currently have as many cool electronics and computing enthusiast magazines as they had back then, we do have a few of them including Make:, Linux Format, and RasPi. (Not to mention the internet and youtube, but sometimes it's hard to know where to start and where to go, and print media are good for that.)
In the area of computer music production, I rather like Computer Music; a typical issue provides music production apps and plugins that you can download and use as well as instructional articles and video explaining how to use them.
Recently I was also inspired by wizardzines.com - I think we need more books (or zines) in a fun and tutorial style!
