To what end?Now show us a picture like that with the keyboard up.
Clearly it takes up space, I was demonstrating the ability to run these apps at the same time which we can't do on phones within iOS. All I have to do is minimize the keyboard to see what is on the bottom portion of the screen. You adjust your workflow to meet what works best for the tools you have. The fact that I don't have to swipe over to a different application, swipe back, then recall the keyboard is a time saving feature. Especially since I can continue to watch / listen to whatever media I happen to be enjoying at the time.
