I have a Canon T1i DSLR camera. With the camera came Windows utility software that lets me connect to the camera and control it from the laptop. The main benefits are: 1. You can see the Live View on the laptop screen instead of the small screen on the back of the camera. 2. You can control the camera remotely for shots such as taking pictures of the night sky without making the camera vibrate. I would love to see a way to connect my Android table to my DSLR and do the same thing. Did find one iPhone app but it only controls the camera when it is connected to the laptop.
