I recently finished graduate school, which anyone that goes to this knows its a ton of research and writing papers. For my needs, I had to have a computer. I needed to have several research articles open and be able to switch back and forth from them on a bigger screen and type at the same time. This could probably be done on the larger iPad Pro, but I dont have that and just have an air 2. That being said, for my day to day uses, an iPad can replace what I use a computer for, for the most part. Right now the storage limitation is my only hold out. I have lots of music, pictures, and videos on my Mac, and currently use an external drive to move files around. I could use cloud storage, but the iPad doesn't let me download files like a Mac does. If this came to be, then I could replace my computer with cloud storage.
