He got it at the Linux store at the mall
It's right across the way from the Apple store.

2. You can purchase Windows 7 online at Best Buy and ship it to the nearest store if you like the physical store experience. Don't be surprised if the Best Buy clerk looks a bit puzzled at you. Neither of us see the point.
