Last year (or the year before, I don't remember) the line wasn't too bad.. I'm hoping the opening of the Apple store here lets Best Buy breathe a little on Black Friday We shall see.
Well, I'm assuming people would have already stormed the Apple store here instead of waiting for Best Buy to open on Black Friday to get their iDevices (Best Buy was the only retailer here that sells Apple products other than iPods / iPads)
Last time I checked, Best Buy charges a slight premium on their Apple products. I had gone in to get a SuperDrive and Magic Mouse/Keyboard, and it was $20 more expensive than Apple D:
