You can't just walk in, buy, and walk out with the retina iPad mini. After discovering online ordering went live yesterday and having heard that supplies were constrained, I placed my order via Apple.com when I saw the 1-3 day shipping designator--didn't realize it was shipping from China and 1-3 shipping days meant several-to-ten to arrival. Then I looked at my current, non-retina mini usage and noticed I'd neared 20gb in apps, none of which were retina, and decided I should probably get the 64GB version anyway. After work today, I went to my local Apple store (in the Shadyside neighborhood of Pittsburgh). I'd checked online and status was that the iPads were available for in-store pickup. Problem is, apparently, they're not yet available for in-store purchase. I walked in, ready to pull out my wallet. Instead of just getting my iPad mini from the back stock, the sales guy led me over to the wall, where I had to use one of their MacBook Pros to place an order via the store on Apple.com and choose in-store pick-up. I then had to wait half an hour, in the store, for the order to process, and for Apple to send me an email that my iPad was ready for pick-up. Only then was I allowed to purchase one. I commiserated with several of the sales personnel. There was no portion of the process that required them for anything, so it wasn't like the guy was playing me for commission. Apparently, the supplies ARE constrained, as has been the rumor, so to prevent people from scooping up several at a time, they're implementing this process. They told me they did the same with the iPhone 5S--at least in that particular location. So if you want the iPad mini with Retina display from an Apple store, make sure you place the order online first. I wish Apple had mentioned that somewhere ahead of time.
