hey everyone! Long (long, long, long) time reader. First time posting. Quick question: I read many are getting their 27? iMacs shipped to them, but they are not available for purchase at the stores. Is this normal? I don't remember a product launch that was shipped to people's homes before it was available for purchase at the stores. If I remember correctly, all iPhones were available in the stores the same day (or earlier?) they arrived to people's homes. Am I mistaken? My concern: purchase the 27" before Dec 31 (tax write-off purposes).
