Retina iPad Mini Launching with Personal Pickup, but No U.S. In-Store Availability Yet [Updated]
Stocks of the Retina iPad mini have apparently yet to make their way to Apple's U.S. retail stores, as all stores are currently showing no availability for pickup, but limited supplies should be arriving shortly. Some of Apple's international stores do, however, already have stock available for in-store pickup, as noted by MacStories' Federico Viticci, who has placed an order for pickup and confirmed with his local store in Italy that supplies are indeed available.
Availability through Apple's online store appears to be holding up for the time being, with the company's U.S. stores showing the same shipping estimates seen at the time orders went live: 1-3 business days for 16 and 32 GB Wi-Fi models and 5-10 business days for all other models.
Update: Some U.S. retail stores on the East Coast are beginning to show availability of Wi-Fi models for Personal Pickup. Many stores have all 8 color/capacity Wi-Fi configurations available at the moment.
Update 2: Apple has now opened up Personal Pickup availability for a number of its stores across the United States. Many stores are, however, still listing no in-store stock, and those that do have stock are seeing quick sellouts of many models.
