Pros
Apple has a name brand recognition like no other in the retail market. When someone sees the company "Apple" on your resume you are automatically put to the top of their list because of their perceived prominence in the retail computer market. When most people think of Apple, they think of the iPod, iPhone, and the lines of computers such as the MacBook, MacBook Air, MacBook Pro, and iMac. All of these products have a simplistic elegance and sophistication in their design, which is shared with the design of the Apple retail stores. You are seen as hip, classy, and cutting-edge by association with the Apple brand.
Cons
While there are a lot of positions open for career development, it is too hard of a goal to achieve if you don't fall into the "hipster" category of people in order to be considered. Tattoos, unnaturally colored hair, hippie clothes, and a penchant for reading comic books and playing Dungeons and Dragons puts you in contention for higher positions in the store over virtues like positive attitude, good conduct, hard work, and reliability. There have been instances I've seen where people have been promoted because they had the right "look" rather than the right attitude for the job. It really makes you dissatisfied with your work experience when a company that will literally do anything for their customers do so little for their employees.
