Pros
Great opportunity for hands-on experience working with new technology. Fulfilling if you enjoy helping people. Good benefits. Healthcare is through UHC unless you're in CA, which is even better for you. Reasonable amount of opportunities for advancement, with preparation and training. The kinds of people Apple attract as employees make for a wonderful group of colleagues. You get certified after training (Apple Certified Macintosh Technician)
Cons
Inflexibility in terms of work hours as a full time member. Constant barrage of upset customers. You are, after all, the customer service AND technician. Weak support from management. Poor pay in comparison to private consultants. High, sometimes unrealistic expectations from management and customers. As one of the more tech-savvy employees, you're bombarded with questions from coworkers.
