Apple references in Wall-E

There're quite some references to Apple in Pixar's latest movie Wall-E. The most obvious one (that I'm sure every Mac user spotted) is the Apple Dong that is the boot up sound of Mac OS X (Wall-E makes that sound when he finishes charging his batteries). Here's a blog post on how that came. However there're a lot other tiny details. Here's a probably complete guide if you're interested.
