The Morrowind map (the physical one you got with the game) was also far, far more interesting and informative than the subsequent ones. You could navigate the gameworld much more easily because the map had more landmarks etc. on it. Plus, you could look at certain things and say - "what's that? I'm going to go and find out..."
I don't really mind the quest markers too much. I'm not sure we can ever really look forward to a map like Morrowind's again, because of the amount of games solid through download these days.
Agreed Morrowinds map was truly excellent and I seldom got lost but that is part of the fun and I got lost because I misjudged locations, you are also right about landmarks you could easily identify where you are and where you need to be now that my friend was an immersive map, loaded with information for the traveler.
I also seriously doubt we get a map like that again for the reason you mentioned above and people want to b guided around by the tip of their nose to a destination or goal. The quest markers have to go, and in its place directions and that is also more immersive.
