I keep responding to rounser, which I realize now is the wrong thing to do, because he's not really interested in the topic of his thread. Let us just note that the original poster's idea, Eberron, and a great many other settings from Arcanum to Discworld do not have the 'Rounser Seal of Quality Mythic Resonance in Roleplaying Award (tm)' and move on. There's really no reason to spend pages arguing a matter of taste.
To make up for participating in this hijack, I want to recommend the Terry Pratchett Discworld series, which, by virtue of being satire as well as fantasy, have a lot of anachronisms, some viewed through a fantasy lens (like the cameras) and some not (later books include a printing press and a telegraph).
In a similar vein of 'modern world as viewed through a fantasy lens', there's Harry Turtledove's The Case of the Toxic Spell Dump, where flying carpets get stuck in traffic jams and the EPA regulates disposal of toxic magical waste.
In the 'some people like it so I really should mention it here' category, you could also try Piers Anthony's "Incarnations of Immortality" series, which features a world where magic and technology coexist - there's an advertising war between cars and carpets, for example. Your reaction to this series will be the same as your reaction to every other Piers Anthony series, so take that as you will.
I hope this has made up somewhat for my part in the threadjacking.
