Pros
Apple is a company that continuously pushes the envelope. It is a lot of fun to work for a company that produces such innovative products. I have worked on many development projects, and get to see my products used by many millions of people. It is really wonderful to be out walking around and see something that you've built in people's hands. The CEO is a very charismatic leader, and is able to whip crowds into a frenzy. Our product release have been compared to Hollywood premieres! I've been at events where I've been able to meet stars that I would never normally see. I get to work with some of the nicest, most creative people on earth.
Cons
Work-life balance is non-existent. You must give your all for the company. Many people end up divorced when working at Apple. Want a vacation? Sorry, not now. Not ever. Apple thinks of employees as "disposable". They burn people out, and discard their empty shells.
