Apple is not going to add pointer support to the iPad. No trackpad. No mouse. They’ve made it very clear that they do not believe in mixing a touch UI with a pointer UI. How is an iPad with mouse support any different from a Surface? It’s not.
I do think we’ll see pointer support in iOS when Apple transitions the Mac to iOS one day. But I don’t think Apple will ever support a mouse/trackpad on iPads.
I recall them also being stuck on a 3.5 inch screen because they thought smaller was better. And here we are now.
