I am out of the country on business and will be back only for a day (Nov 10th, Saturday) in the Bay Area, before I leave on another trip on Sunday. I want to stop by an Apple store and get the iPad mini on Nov 10th and use it on the plane for my next trip. Questions: 1. Will the iPad mini be in stock when I go to the store? 2. Is there an advantage to ordering it online before hand and then doing an in-store pickup? 3. I am looking for the 16GB wifi only model (white or black - not sure). Have any of you heard of any shortage in stock of these models?
