Wondering what people's experience has been when buying an iMac, which I will be buying soon. Did you go with MacMall? Apple Store? Some other place? What were those experiences? Another questios - did you have to pay sales tax at the these stores? I live in Georgia, where Apple actually has physical stores so I think I would have to pay sales tax if ordering through Apple but I'm not sure if I would through MacMall. Anyone else run into this? I'm getting an iMac either way. Just wondering.
