This is actually why I've got a Moto G on order. This will be my first smart phone. Before I heard about the Moto G I always assumed my first smart phone would be a Nexus device, because I refuse to sign a carrier contract and I would rather have a dumb phone than carry around something that cost $600 in my pocket every day.
But with the Moto G, I get a cheap-ish device with all the features that actually matter to me (high res screen, good camera, reasonably fast processor, decent amount of RAM) and it doesn't come with a contract or a crazy price tag.
I saved $150 over buying a Nexus 5, and I doubt I'll even notice the difference (if anything, I'll like it better because, IIRC, the Moto G is a bit smaller than the Nexus).
