How is Apple Related to Pixar?

I was looking at some information about the all new iPad the other day and then I remembered the relation that there is between Pixar, the company that makes the best animated movies in the world, and Apple, the company that brings us the best computers and electronics in the world. You may or may not know that Pixar's former C.E.O. is Steve Jobs, who is currently C.E.O. and co-founder of Apple. Similar to A113, Apple is sometimes hidden in Pixar movies as well. Need proof? Next time you watch Toy Story 3, look carefully at the screen of Andy's laptop. He is using iTunes. Also, in the scene where Woody and Bonnie's toys are surfing the web, they are using a Mac and have a Safari window open. There could be more hidden Apple references in other Pixar movies, and at least now you know the relation between Pixar and Apple!
