Pros
Well, for instance, I wore board shorts to work today. The environment is mixed and ALWAYS lively. Due to the stress involved, all the employees tend to shrug it all off with one another, meaning they all tend to have great collective sense of humor. For those on the sales floor, the absence of commission is a great way to have team unity. For trainers, having actual time to learn at work is something that I had never heard of and for techs, the ability to make important decisions with very little micro-managing is a testament to the trust Apple has towards it's employees. At any given Apple Store you will find cheer and unity despite the stress of dealing with entitled and spoiled consumers this has much to do with the craft behind the hiring process.
Cons
At the Retail stores, as a tech, growth is minimal, albeit a unique and novel environment to occupy; the pay (which is competitive) is NOT worth the stress. To Apple's credit, the pay is actually fair but in my opinion, the demands put on the techs or Genii are not fair in comparison.
