My favoritest site in the world, iFixIt, just tore up the MacBook Air to assess its unique innards. What did they find? Well, it’s pretty hard to open the case but thankfully most of the parts that will probably break are sequestered under the back panel rather than under/over/around keyboard and speaker parts the way the PowerBooks were. This will definitely come in handy when batteries start blowing and hard drives spin themselves into oblivion.
