He's right - the market wants embedded batteries, although perhaps not directly. Embedded batteries have improved price, battery capacity, water proofing, size, and strength. If the consumer really wanted a removable battery and all that that entails then there would be more phones that offered that. The reality is people misjudge what all that entails. By all means, I would love to just make the iPhone battery directly replaceable without any compromises but that's not reality.
