I like the zooming ability in Civ4. It works like a City view, it may not look pretty, but it sure is better than Civ3. And if you are running Civ4 on the highest graphics, it doesn´t look that bad at all. I mean it´s not like you can´t tell what is what. I hope Civ5 will include similar options for city view as in Civ4, and with better graphics.
