Pros
The best reason to work for Apple is to abuse the discount. 25% off retail is price impressive. Thats 700 dollars off the 2499 macbook pro model. This really helped me throughout school only having to work for retail part time. The other great reason is debit card for caltrain, bus, and bart. Apple gives you 100 dollars in the form of a credit card that you can use to commute, or joyride to the city on your days off.
Cons
Growth is hard. If you're gonna go into this job in retail, expect it to be temporary. You can't really move up in the company quickly. It's contradicting on how they work. If you're the best at your job, they try to keep you there to help store numbers. Yet if you're bad at your job, they say you need to improve to get the other positions available. Don't assume working for apple retail now gives you an advantage to get into apple corporate. It no longer works like that. Retail doesn't mean crap.
