I feel like a good illustration would be a bicycle.

1. My bicycle works fine, a little slow, but it beats walking, and requires little to no outside resources or upkeep.
2. My neighbor, Joe Microsoft, slaps an 80cc motor on my bike. It’s a lot faster, and less work for me, and Joe keeps it full of gas and tuned up, and fixes it when it breaks.
3. I need Joe now to support my biking. I no longer have the resources to do it at this level, but Joe does.

Is that about right? Are we selling open source for speed and convenience?
