There is some type of actual keyboard with keys, for the ipad sorta like the MacBook. In a few ways, the iPad is actually a better investment. If you get the MacBook, it is less portable. If you actually do get the keyboard, it is easy to detach and turn into a normal iPad. If you do this you can also make sure that you are always prepared.
You can also buy keynote. Keynote is like PowerPoint which you can actually make for school, and you can download all of that.
So,honestly the iPad is a better investment.
