I am planning to buy a MacBook for making and selling app for statistics. The app would have to create charts and tables. Do you think a 12" MacBook is adequate for this purpose? Or should I get a bigger 15.4" MacBook Pro instead? I would rather not use an external monitor since it would clutter my small room. Also, do I need a Core i7 or would a Core m3 be adequate? Regardless of my choice, this would be my first Mac although I have been using my iPad for like 8 months.
