I've never understood why anyone would use an iPad to take pictures anyway. It's like the most awkward camera in the world. The only reason to bother with a camera on an Ipad is the front facing camera for FaceTime.
I use the flash on the back of my cell phone as a flashlight if I need a quick light, but it's somewhat awkward to use as well. I much prefer a regular flashlight that I can set down or hold in my teeth so I can use both hands. Even the cheapest $5 dollar led flashlight is better than the flash in a phone or tablet for almost any task, not to mention smartphones and tablets are already power hungry enough without using a very bright led!
