To use your iPad for studies and business use, you need enough storage capacity. These iPad models have 128GB storage or more, so that you can save all your files and always have them near. On the medium-sized or large screen, you have enough space to work on all your reports and emails. Buy a keyboard cover and place your iPad upright so you can type reports more comfortably. With a stylus, such as the Apple Pencil, you can easily make notes just like with a pen on paper.
