The iPad lineup is confusing. There are too many models.I have tried to focus only on 4 models which I think are essential, using the famous Steve Jobs grid.
It doesn’t hurt to have extra models, but it’s just a little bit less Apple-like experience when you shop. This complicates the accessories range and makes a choice more difficult. Apple engineers have to spread their focus across many models instead of focusing on quality.
I think the iPad Pro 11 and the iPad Air need to be removed from sale.
