🔗 Apple’s Presto system is even more sophisticated than it appeared // 9to5mac.com

When a customer buys a particular SKU (one example of a particular iPhone model, storage tier, and color), then the system prompts staff to update another one. This ensures that no matter what a customer wants to buy, there is always at least one up-to-date model in stock at any given time.

I was very curious about how stores would handle keeping the whole stock updated. One at at time for each SKU certainly seems more managable.
