Why are you so fixated on expecting the iPad to be a replacement for a SLR, DSLR or other camera? If you're that worried about the camera and flash aspect, you will likely be more satisfied buying something designed exclusively for that function, such as a camera. Even with my iPhone, I rarely find a need to use the flash indoors.
I'm not fixated
I'm simply saying any general purpose device that has a camera on it, and is designed to be used at any time should naturally have a flash.
It's not really an opinion it's just totally obvious and logical it should have as that's what goes alongside a camera lens. A flash to illuminate the scene when it's too dark for a clear image to be captured.
The iPad will have a flash.
Some time after a flash gets fitted and people are used to the iPads having flash's for years, it will seem idiotic to want to remove it.
And please don't think I'm making this point as I think you should use the iPad's for taking pictures all the time, though if you do and you like it, then great
I am again saying the best camera, is the one you have in your hand at the moment you wish to take the shot.
If you have the iPad in your hand and something happens NOW you want the best you can get from the device you have.
We could a few years ago been having the same argument about a Camera on a mobile phone and people here seem to be the type who would of said OMG what a stupid idea a camera on a phone! what an idiot. If you want to take a picture then take your camera with you like any normal person does.
But no one seems to be saying that now.
