Pros
excellent products, large emphasis on design and branding. second-rate is not acceptable and being an industry leader in digital music sales and product design is something that everyone is very proud of. People tend to be friendly and extremely intelligent, with a great work ethic at a very young age. Almost everyone works at what they love doing. Also Apple is good about shifting you to other parts of the company if you aren't happy. They want to keep employees.
Cons
the process of getting to the final product is gruelling and inefficient. Lots of politics leading to strange partnerships and promotions based not on quality but on starstruck management caving to external parties.not paid as well as other companies in Silicon Valley, with long hours, never really being "off" work, strange management hierarchy… iTunes in particular seems to be chaotic and suffers from a noticeable lack of competent management on the upper levels, with a lot of grandfathering-in of people with no music industry background and promotions seemingly based solely on seniority and random luck.
