This is a photo from my iPad Mini. Two-handed, it's is easy to hold still, thus the picture is sharp despite the slow 1/15 second shutter speed. (And top aperture, 2.4.)
But: notice how grainy and unsharp it is, folks. And this is despite the low ISO setting of 250! Even pocket cameras have delivered better results at ISO 800 for the last few years. In other words: The Mini has a very small camera with a very tiny sensor, meaning it's not good in low light. This of course is the price for the wonderful slimness of the Mini, but you need to take it into consideration if you think that the Mini can replace your pocket camera. It can't, unless it's only for snapshots for the web. (It's just 5 megapixels too.)

I downloaded the photo and looked at it full size. It's not too bad for grain. Are you sure you are not looking at it oversize on your monitor?
Well, Blogger scales it down from 5MP to 2MP, that makes the grain and unsharpness much less visible.
But of course few web images are bigger than 2MP. And in better light it'll be better.

I was just a little shocked to see image degradation at only ISO 250, to the degree that normally is only seen at maybe 1600.
It's a good camera for the size, but it *is* a very little camera indeed. Just think: it fits in a space a quarter the size of a thimble!
