Exactly. I've had iPads now since the 2nd model, and have used front camera about 2% of the time, and the rear about 98% of the time (great for snapping whiteboards). But, truly, I don't use the cameras much at all, and would prefer to not have fancy cameras on an iPad. The phone is where the fancy cameras should be. And, I also carry a 'pocket' camera with far better close-ups, better video, and more storage and effects which I don't use as much, but is indispensable when it is.

The phone already is where the fancy camera is. The iPad back camera is far worse than the iPhone's cameras.
