There are really pros and cons with whatever equipment that you use. The downside of a DSLR would be cost, size and weight for starters. If it's too big and heavy to carry around, then it doesn't matter what it is - it won't be used. Also with interchangeable lenses you'll eventually get dust on the sensor. Not a big deal to clean it but something that needs to be done from time to time. All in all, there are some significant advantages to using a DSLR but sometimes I prefer my compact.
