Pros
The work, at its best, is truly inspiring. It's really all about getting to do interesting projects that will touch millions of people. The fast pace provides an adrenaline rush that, deep down, I seriously enjoy.
Cons
I'm not convinced that Apple cares about its employees, and things are getting worse all the time. In the last year, free dinner was moved from 5pm to 7pm, our free apples were taken away, and food prices were raised. A large, delicious salad from the salad bar used to cost $4, and overnight it went up to $7. I have little hope that things will be better when Apple Campus 2 opens next year. Additionally, the campus (if you could call it that) is now so large that I often spend hours of my day just shuttling around to different meetings. My productivity suffers.
