Hello everyone. I am wondering about your experiences in buying the MBP in Apple Stores (specifically the Michigan Ave. store in Chicago). In general, how has availability been this past week or so? I figure I'll call before I go, because it's a two hour drive for me, but I would hope that if I went in this Saturday, I could get my machine. My more important questions is this: Will the staff allow me to open and unpackt he machine there in the store, and check it out before purchase, or at least let me check it out there after i purchase it? I am worried about the screen buzz/whine, and other potential damage/DOA conditions, and i would hate to drive two hours home to discover the horror of the squealing display!
