The biggest advantages of an SLR are IMO control and responsiveness. You can get better image quality as well, but compact cameras are getting closer in that department these days.
You push the button, the shutter goes click instantly - none of that push the button and wait... wait... wait... click, by which time the thing you were taking a photo of has probably moved.
Obviously to get full advantage from the extra control you need to understand at least the basic principles of it, but its not that hard. And most SLRs still have auto modes for when you can't be bothered. An SLR won't turn a crap photographer into a good one, but if you have an interest and learn how to use it then you will get better results.
