I use my iPad complementary to my Macbook. Reading documents and taking notes with the pencil mostly. Scribbling down thoughts and concepts that sync over Onenote to my other devices. I have no desire to use it as a Laptop replacement and am not sure why people would want that. I can acknowledge that some people use an iPad as their sole device to work which I think is fine for many, but Software Engineers have such complex usecases it's hard to make a device like the iPad be perfect for them without compromising it's main user base.
