From 2006 to the very latest in 2010 here's a look at what's inside 57 Apple products. What caught my eye was this article about the new Magic Trackpad. AppleInsider shows the innards of MacBook, iPad, iPhone, iPod, and more. There was one little problem: clicking to go on to page 2 didn't work. An email to their webmaster Kasper Jade was nearly instantly replied to and fixed.
Curiosity led to the iFixit site. They show you how to troubleshoot, they sell parts, supply repair manuals, help you recycle all sorts of things. They invite you to contribute your knowledge. Interesting!
