Steven P. Jobs established Apple University as a way to inculcate employees into Apple’s business culture and educate them about its history, particularly as the company grew and the tech business changed. Courses are not required, only recommended, but getting new employees to enroll is rarely a problem.
Although many companies have such internal programs, sometimes referred to as indoctrination, Apple's version is a topic of speculation and fascination in the tech world.
Mildly interesting puff piece on Apple, but what I found kind of hilarious is how the author chose Apple's mice as a shining example of Apple's philosophy. Apple makes some great, defining products - but Apple's mice are absolutely horrible. The little mice timeline also curiously omits the most horrible mouse in computer history.
About 7-10 years ago, I was talking to a sales person at the oldest and then-largest Apple retail chain in my country (founded by the first Dutchman to own a Mac). The sales person was obviously a fervent Apple fan, but as we were detailing my Mac purchase, he said "do you want an Apple mouse, or a mouse that works?"
The first thing I do when I buy a new Mac is toss out the Apple mouse.
