I can't imagine going to an all-purpose store like Best Buy for something as special as an Apple product. The ambience is totally different, the staff with whom one deals significantly more knowledgeable about and interested in their product(s) and the entire experience on a Launch Day in particular is just so unique and delightful. That said, I realize that not everyone has the choice, as there are indeed areas in which there are no Apple stores or getting to one involves a significantly long drive. Sure, in that case Best Buy works. If in an area where both stores are available, I will choose the Apple store first, each and every time.
