I would quit too. I love Apple products but they come at a huge human cost. One of my best friends works there and he's always extremely stressed out. He works like 15 hour days, 6 days a week. He's constantly bailing on his obligations because Apple decides to run a conference call at a ridiculous hour of the night, or right before we go into a theater to watch a movie. Nevermind the China trips that get dragged out for weeks. I've heard from him on several occasions that there are few people who have worked at Apple longer than a few years because of the burnout.
