This is such a common misunderstanding of Jobs. Jobs wasn't an altruist. He believed that "great artists ship" and was hyper-focused on releasing profitable hardware and software. The difference is that Jobs believed in releasing hardware and software sufficiently excellent that people would pay a justifiable premium for it.
Remember, Jobs killed the Newton project because it was unprofitable, even though it was an incredible (and constantly improving) tech achievement that was improving people's lives. Jobs brought the Newton technology back into R&D, and refined it until it could be redeployed in truly profitable touchscreen devices like the iPhone and iPod Touch.
It's the brilliant Steve Wozniak, not the marketer Steve Jobs, who would have bankrupted Apple by focusing on improving people's lives and releasing innovative technology with minimal regard for profit. Supply chain Tim is more like Jobs than many today like to admit.
