All the other specs aside, the idea of having the dust resistant coating on the sensor and the sensor cleaning vibration feature sounds very nice. I haven't played with it or know how well these sensor cleaners work, but dealing with dust on the sensor is one of the more annoying things about d-slr cams. You are undoubtedly going to get dust on your sensor at some point and will then potentially see that dust in many of the images you take. You won't see it in many pictures, but if you take pictures with the sky with small apertures, you'll see the spots pretty clearly. I just photoshop out the spots in the pics I take where the dust spots are obvious.
