iPad Model # Confusion

Both model numbers refer to an iPad Pro 11" (2nd generation). In particular, it's a 128 GB model with Wi-Fi only, in Space Gray. The 2nd gen iPad Pro is the current latest / newest generation iPad Pro.

One model number refers to a demo unit, which are used in Apple Stores, those are not for sale. A third-party sale of those devices is not wanted by Apple. Demo Units are loaded with sample files. That contains calendar entries, mails, apps, photos etc... for a potential customer to explore.

But both model numbers refer to the same device. Same generation, size, capacity, color etc... In Terms of Hardware there shouldn't be a difference.

Really…? So I must be mistaken that I’m typing this on a 4th generation iPad Pro, then…? I have a 2nd generation, it doesn’t charge very well so I bought this. It was released in 2017. The 3rd generation model was released 2 years ago (2018). This is the 4th generation. The original iPad Pro was released on 2015.

So, no, the latest isn’t the 2nd generation.
