I can take hundreds of pictures at one time. Sometimes I'll go "Oooh. This looks interesting!" and it doesn't turn out the way I want it or it wasn't as cool as I thought it would be or I wasn't holding my camera steady and it became blurry or the angle was all wrong or the flash made everything to bright or the lack of flash made everything darker than it really was. Imagine how many rolls worth I'd waste! I usually end up with more wasted shots than good ones I can use. With digital I don't have to wait and see if anything turned out and end up with dozens of useless photos that I'm going to throw away and are going to be in a landfill forever.
