Why there's so much empty space surrounding the battery? https://d3nevzfk7ii3be.cloudfront.net/igi/O2r5KUFwY4HHc51F.huge It looks like if all that wasted space (and that ridiculously thick diagnostic port bracket) was used for bigger battery, the battery life would be 20-25% longer (almost 24 hours) or would allow the always-on low energy clock face for the same 18 hours. This wouldn't have happened if Steve Jobs was alive: http://www.theatlantic.com/technology/archive/2011/10/in-praise-of-bad-steve/246242/ "When engineers working on the very first iPod completed the prototype, they presented their work to Steve Jobs for his approval. Jobs played with the device, scrutinized it, weighed it in his hands, and promptly rejected it. It was too big. The engineers explained that they had to reinvent inventing to create the iPod, and that it was simply impossible to make it any smaller. Jobs was quiet for a moment. Finally he stood, walked over to an aquarium, and dropped the iPod in the tank. After it touched bottom, bubbles floated to the top. "Those are air bubbles," he snapped. "That means there's space in there. Make it smaller."" Even waitresses would understand this.
