So you're an employee at Microsoft, more specifically the Zune division, the people responsible for Microsoft's entry into the MP3/mobile video player market. You are a good, loyal employee who puts in their hours, does a good job and in general works very hard to help make sure the product is a success. There's only one problem.
You own an iPod.
You try and disguise your treachery by keeping the device in your pocket as you work through the day, you've even purchased a pair of non-white headphones so as not to tip off your supervisor. But it's all for naught, they're on to you! However, instead of doing random sweeps of the cubicles looking for the contraband devices, they've taken a kinder, gentler approach to the problem. The approach is like the teacher saying they'll turn their back on the classroom, and whoever stole the chalkboard eraser can come up, place it on the desk and not get in trouble. Microsoft has placed an "Amnesty Bin" for iPods outside the main entrance to the Zune building. Just toss the iPod in the box and you're in the clear!
Ok, maybe it's not that dire, maybe it's just a little bit of fun the Zune team is having, a little friendly jab at Apple, but the more nefarious scenarios are a lot more fun to think about.
