So long as you're seeing text on your console, you have a need for text
streams.  They make life a lot easier for programmers, because otherwise
we'd be popping characters into a big array to draw on the screen, like
those poor DOS programmers who made interactive full-screen applications
(and yes, that really is how it's done).
