that's simply wrong, if i had a dolar every time i heard that.. walking to frame is fundamentally wrong, focal length has no effect whatsoever on anything else but framing (and dof, but not the point right now). a zoom is good because, as albert pointed out, it allows you to frame precisely what you want from where you want it, because perspective is given by your distance to the subject: if you walk to change your framing, you will also change perspective, and most probably the angle of view as well, so you are changing too many parameters to be in control. one should choose the distance first (for the wanted perspective), the angle (and thus point to shoot from) next, and the lens focal length after all this.
maybe i'm an old timer, but it's just the way i understand things, fwiw
Quote: Using zooms I eventually realized that I usually shot at one extreme or the other, seldom using anything in between.
My solution was easy: Get fixed focal length lenses. Better optical quality, faster speed and lighter weight sweeten the deal.

interestingly, i have realized something similar, though not exactly (i do use stuff in between), what i don't notice though when i make this assesment is that the zoom allows me to frame precisely, yeah, it was a "30-ish focal length", but choosing 27 instead of 31 allowed me to frame exactly how i wanted.
funny enough, though, i prefer fixed focal lengths myself
("old timer" again, i guess)
