Hi there, I am in need of some advice! I already own a MacBook air 13", and I need to start using some sort of device for my architectural drawings and research. I went into Apple and saw that they do a digital drawing pad that links to my Mac so I can complete my drawings. But, the staff member also showed me their new iPad pro and gave me a demo with a drawing app called 'Concepts' using their new apple pencil. I can also get auto cad and other design apps on their as well. Basically, what I want to know is whether a MacBook Air 13" or iPad pro is better for Architecture Design!
