One cool thing about all of Meteor's magic is that it's quite understandable. Chris Mather's EventedMind and Arunoda's MeteorHacks are good resources for looking behind that curtain.

In my experience, once the magic becomes more of an understanding of the Meteor-y way of doing things, then debugging and maintaining isn't any harder than a more traditional architecture.

I wouldn't say that Meteor is a suitable framework for any type of app, but I would say its design is suitable for a lot more than just prototyping and games (with a pre-1.0 caveat).
