If true (we’ll see), the iPad cameras are, by intended use VIDEO cameras. Chat and AR cameras. Not still cameras. That make sense to me.
Casual still snapshots are a nice extra, not a main function of something so large as an iPad. (Neither is camcorder use for that matter.)
Video applications that make sense with a tablet are FaceTime (showing someone what you’re seeing) and Augmented Reality. Both will get more and more used over time.
While using something so large as an iPad to capture memories will be an ever-shrinking rare usage over time, as more people carry phones (or, say, cameras

) that do that job.
ummm no.
My friends pictures vs my iPhone 4 pictures can't even compare.
Megapixels are just as important as how you use them.
You misread me.
I said VIDEO camera—specifically video, not stills. The iPhone 4 as a
still camera IS far better than the low-MP iPod Touch, as you say. (A high-MP camera does carry problems even for stills: it can be high-noise and waste memory/storage for no reason but marketing. But the iPhone 4’s still camera is indeed excellent, and has replaced my old standalone camera. Its rear-facing HD video is good too—just not as good as the iPod Touch in the 2 ways I mentioned. Demos of this are online.)
My post was about how, on the iPad, moving video would be more important than still photography.
I don’t want, for instance, to be viewing a scene in AR (or showing it to someone on FaceTime) and have my view restricted because it’s a high-MP sensor dedicated to stills over video. (See my discussion of the field of view being cropped on iPhone 4 video recordings because of their high MP.) Sensors are specialized for either stills or video, and I know which specialization I want for an iPad!

Yes. Any old camera will be nice for capturing a memory if you’re at an important event and don’t have any other camera. “The best camera is the one you have with you.” The day will come when I capture some memory on my iPad 2 because someone else is playing Tetris on my iPhone! But it’s a rare use. NOT the purpose of the camera being there. I really hope it has a rear camera, but frankly I will use it rarely compared to the rumored front one.
