It might be a bit too archaic now, as a lot of the terms and technologies discussed were on the way out even when the last printed version was published, but I did find The New Hacker's Dictionary very enjoyable in this sense.

Programming Pearls might be another good book that promotes enjoyment of computing; certainly a bit more technical, but I think plenty readable for someone interested.

I'd add in that list the New Hacker's Dictionary edited by Eric S Raymond http://www.amazon.com/The-New-Hackers-Dictionary-Edition/dp/... - (aka the Jargon File http://www.catb.org/jargon/html/ ) It includes many computing terms invented over the years with their meanings and origins. You can learn a a bit about computer history by readin it.

It's increasingly outdated as an actually useful resource, but The Hacker's Dictionary has long been one of my favorites, and should still be fun and educational from a historical perspective:
