If you ever used a flm-based SLR camera, you'll want the digital version. Saying point-and-shoot cameras take as-good pictures is like saying your disposable Kodak is as good as a Nikon SLR. The differences are just as great. But you do need to learn to use them. The various lens, filters, aperture, and shutter speeds work exactly as they to in the film versions, including the ability to vary the focal field depth.
Don't get overly concerned by pixel counts. If the lens doesn't focus correctly, you can have twice the pixels and worse pictures. The ccd is of better quality in a DSLR and there are many accessories available to extend the usefulness of the camera. These include filters, slave flashes, various mounts, remotes, etc.
