I intended to order 64GB silver. When I was able to get the Apple Store app up and running ~3:10am EST, silver delivery was already delayed a week and no in-store pickup was available in my preferred location. So I ordered 64GB SG for in-store (Nov 3 delivery was also available but I’ll be on the road on Friday, traveling to the city where I chose to do the pick up).
For me the kicker is the black front bezel. I’d be willing to try other colors now, after having purchased black/gray almost exclusively for years.
