What are you guys complaining about.
Nobody's will be taking pictures with an iPad. It just doesn't make sense. I think that the rear camera is also for facetime (so the person you're talking to can see exactly what you are seeing. That's it. What more do you want?
You guys seem to complain just for the sake of complaining. Why do you need a 5 M.P. camera? Because the iphone has it? Sounds fallacious!
A 1 MP camera likely won't have the resolution needed for apps like Word Lens, QR readers, and other document scanning/reading/analysis apps to work reasonably well.
