If you have the camera and housing already, it will work fine. It has less pixels than current models and probably less focus points, but most UW shots are spot focus and there are plenty of pixels to take nice pictures to post on forums, facebook or display on your computer. If the camera and housing combo is available cheaply, as a package, it would be a worthwhile purchase. If you have only the camera, or have to pay a premium for the camera or housing, your investment in something more current wouldn't be that much more and you should get something newer.
