Today I went to the Apple store to buy this:
I also bought a laptop stand. As I was finishing my shopping I set my products on a counter, whipped out my iPhone, went to my Apple Store app, and paid for my items with my iTunes account.
If the products had been smaller, I’d have thrown them in my purse and walked out, but I needed a bag. The salesgeek was happy to give me one, and out I went. The whole thing took about ten minutes.
It was the most enjoyable shopping experience of my life. No lines. No waiting for someone ahead of me to pay for their items with a temporary check from the Bank of Tehran. Just zip in and zip out.
