I don't understand this comparison. Meteor makes things simpler and removes a lot of low-level complexity. It makes software development simpler. By "some people want Windows", it sounds like you're suggesting that there's a better platform/framework for web development that's "plug-and-play" ready -- so easy that a non-developer could use it. I actually think that Meteor is the closest thing to this, and is the very best starting point for new developers. To this thread's question, it's also great for large applications. But at the end of the day, it's still web development -- you need to learn JavaScript, Mongo, html, CSS.
