The only difference between the two, according to the report? The high-end model will get an 8 megapixel CMOS image sensor, while the mid-tier version will get only a 5 megapixel.
The problem is that the camera on the iPad is more of an afterthought than a feature that will prompt users to pay an extra hundred or more dollars to upgrade to a higher-tiered device. On the current iPad, the rear camera captures still photos at less than a megapixel, which is fine, because if you are using your 10-inch tablet as a camera for anything other than the odd emergency situation or when making a video call, you are doing it wrong. Especially since most people with iPads are walking around with 5 to 8 megapixel shooters in their smartphones anyway.
Boldfaced emphasis added by me.
That is such smug, short-sighted thinking that I was compelled to do this post to argue against it.
