Personally, I never got into the whole "magic is not special, it's technology" of Eberron... I like the fact that the PCs are some of the most visible spell casters in a fantasy setting (shy of the real shakers and movers behind the scene) and the reason NPCs call to them for help is because magic is not technology and is not mundane.
Just to explain the philosophy behind Eberron in more depth, because hey, I like Eberron...
What inspired Eberron was the fact that in 3E D&D - the core system when Eberron was developed - arcane magic
behaves like a science. It is 100% reliable unless you get punched in the face while casting a spell. It is repeatable. It uses a system of physical and verbal components. One wizard can learn a spell from another wizard, or create a new spell on his own. Given these facts, it seemed strange that magic is never used in a more scientific manner and applied to the same sort of problems we solve with technology - transportation, communication, medicine, warfare.
With that said, another of the core principles of Eberron is that
player characters are rare and remarkable. It's not a world where the bartender might be a 10th level fighter or where there's a bunch of 15th level wizards hanging out playing cards. The bulk of the world have a level or two of commoner or expert. Most professional spellcasters are adepts and magewrights. And even beyond that, it's rare to encounter any magic over third level. Eberron is "wide magic" as opposed to "high magic". The streets are lit with continual flame and there is a lightning rail, but teleportation is still a remarkable thing. Tied to this is the idea of creating new spells. While it's POSSIBLE, it represents the sort of genius most people simply don't have. You may be able to send an army down the lightning rail, but it's an army of 1st-level warriors and there are many problems they simply can't solve; and that's where the amazing player character comes in.
So your player character wizard
IS one of the most important spellcasters in the world. You are a person who could make innovations and do things that have never been done before. You are marked by your limitless potential, and by the time you're tenth level the powers you wield will amaze people. Sure, they understand the PRINCIPLES of what you're doing - but they may have never met anyone who could do what you do.
Anyhow, I'm not trying to change your opinion about Eberron - but it is certainly the case that it's a setting driven by the idea that the players ARE big damn heroes and the only people who can solve the big problems.
