I just flew United Airlines from Melbourne to Chicago. Full flight. My 13″ MacBook wouldn’t completely open, without hitting the seat in front. Did they just shrink the Economy class seats? The in-flight entertainment system crashed both during SYD-LAX and LAX-ORD and refused to reboot (oh, I hope they maintain the planes better than these units). After cursing about being unable to use my computer properly, I realized that it was not a problem, but the solution. A single MacBook battery (4000+ mAh of power) can recharge an iPhone or iPod Touch enough to fly nonstop around the world several times. In Airplane mode, the iphone/ipod takes very little power. The screen is crisp. I watched several good videos, caught up with my favorite podcasts, played games, wrote this blog post, and read a few books (in color, unlike on the kindle). It was liberating. Why even bother with in-flight entertainment when you can bring along much better quality stuff? (Added: Airlines should get out of the business of providing poor quality entertainment, and instead focus on providing the two resources that are scarce: electricity and a wifi connection).
