1. I haven't tried do do this, but it doesn't sound right. You can't pull from an external drive and import on the iPad? If not, this goes onto my list. However, this is more of a "I can't do it like I can on a Mac" item , so...borderline
2. Valid, but another "I can't do it like I can on a Mac" item , so...borderline because AirPrint does exist
3. An iPad version of the Mac App should suffice. This is a Microsoft Surface-y, macOS-on-iPad-hardware kind of request. Be specific to WHICH app you want to use but can't
4. The task here is installing apps. The how is what you take issue with.
5. Fair. I hope M1 addresses that, but it goes on the list.
6. Again, you want Mac-like multitasking, not iPad-like multitasking, but I'll allow it onto the list
I think the iPad will NEVER be a device for you. Given the list above and that statement, it seems it's more about how you do things than what you do.
