I drink rooibos tea when I want the flavor of tea without the caffeine of regular tea. A cup while watching nighttime TV won't keep me awake for hours like regular tea does. I like it in the single-serving packs so I don't get the flotsam from making it with a strainer. Although, really, I don't object to tea flotsam if it doesn't get between my teeth, since rooibos can have sharp little splinter-like bits, the bag is a real convenience.
