Constellations

I've heard that the stars we see today could have gone out millions of years ago, we just haven't stopped seeing the end of the light yet. I think that's such a negative way to look at it. Why not say, "we could be looking through time and seeing an image that doesn't exist anymore" or "that one looks like a W"?
Speaking of the one shaped like a W, anyone else really like that one? I always look for it when I'm out for late walks or driving etc. It's always on the opposite side of the sky as Orion.
Come to think of it, I think it's more like an M.. I could never tell if I was seeing upside down or right side up. Damn you Casseopeia.
