Battery Life: The iPad's Killer Feature

One thing that didn't happen during my iPad trial? Tripping over charging cables. The battery life of the iPad, including the iPad mini that's become my primary device, is taken for granted a bit. But in a school, knowing that your device will last all day, no matter how you are using it, is transformative. I'm currently at 10 hours of use, and still have 32% battery remaining. All hardware requires trade-offs (like the non-Retina display I'm using right now), but I for one am glad Apple has prioritized battery life. Less than 10 hours would be a huge disappointment now.
