My .02 for the day......
Cornfield had a good point about distance. If you use 35mm, you can get a pretty good medium range zoom lens rather cheaply. I use a 35-200mm as an everyday on my work camera, and it works relatively good as a general purpose lens. You can get close without seeing your reflection in the shot. Also they can come in handy when the subject of the picture is a little farther away, and you cant get close enough for a good shot. (The girl onstage with the big manifolds.) Some of the newer digitals have rather good zoom capabilities, and work just fine in the same situations.
