You get to see the image the sensor is capturing in real time, you see the effects of any white balance changes or different picture styles or even exposure adjustments. You get a histogram in your viewfinder, more image info than you ever see in a DSLR viewfinder and you don’t have a dirty great mirror clanking up and down every time you press the shutter release.
