Exactly. For my Pentax MX, I have several standard lenses - the 50mm f1.7 is a cracker and respectably fast, whereas the 40mm f2.8 Pancake isn't very fast and isn't as sharp. But it does allow camera and lens to fit in a jacket pocket, so is incredibly useful, and I see this lens in exactly the same way. So what if it's a little slow? So what if it's not as sharp as other lenses? It'll get you good enough pictures when nothing else will, and for me, that's the whole ethos of 4/3.
