Defining the purpose of your photography will help you decide what equipment and training is best for you.
I am a professional portrait photographer and I am in the DSLR camp. My images are meant to be printed. I like DSLRs for many reasons including more creative freedom both in camera and post production as well as better print quality.
A few quotes by Ansel Adams, who was primarily a landscape photographer.
“You don’t take a photograph, you make it.”
“Photography is more than a medium for factual communication of ideas. It is a creative art.”
“The sheer ease with which we can produce a superficial image often leads to creative disaster.”
“The single most important component of a camera is the twelve inches behind it.”
“Photography, as a powerful medium…offers an infinite variety of perception, interpretation and execution.”
“There’s nothing worse than a sharp image of a fuzzy concept.”
“I am sure the next step will be the electronic image, and I hope I shall live to see it. I trust that the creative eye will continue to function, whatever technological innovations may develop.”
"No man has the right to dictate what other men should perceive, create or produce, but all should be encouraged to reveal themselves, their perceptions and emotions, and to build confidence in the creative spirit.”
