The starfield in Elite is not just a decoration, it shows the stars that should be visible from your current location, and they increase in size and luminosity according to each actual star luminosity and size. This also allows me to recognize famous real stars in the skybox many jumps before I get there (provided their big/bright enough and I know where I'm going and not just flying randomly). Also I have found some giants and supergiants and some very cool places by actually following stars in the starfield, or by noticing big bright blobs and looking for then in the galaxy map.
Also, in space there is a lot less light pollution than down here on earth, so stars are a lot more visible than looking at the night sky from down here.
I personally love ED's skybox, but of course its a matter of personal taste. I only think the space should be darker in all the spaces between the stars, its a bit too grayish. And the dark side of planets is far, far, far too bright, but this is a whole other discussion...
