Maybe Apple is secretly sending these folks out the door as spies to work at Microsoft!
Seriously, Apple is known for having very, very, brand committed users. I'd think that the employees in their stores are even more committed to the Apple platform than the average user. This person is a committed Mac user and they now find themselves working in a Microsoft store. So they will have Apple zealots working in their Microsoft store. It would be like hiring the guy in the "hey, I'm a Mac" commercial to sell Windows. I can see a new Apple commercial coming from this.... the "hey, I'm a PC" guy talks the "hey, I'm a Mac" guy into helping him sell his PCs.... think of the humor! If he's just honest with what he knows to be true, he'll talk everyone that comes into the store into buying a Mac instead of a PC. What's he going to say when someone asked him which one is going to be easy to use, reliable, and be less prone to viruses? Umm... the Compaq one? I think not.
