Have you seen anyone take pictures with an iPad? it's really stupid. Especially if you consider that in Dutch we call someone who is oblivious to things/concepts/ideas/knowledge that should be obvious, as having a "bord voor zijn kop" which translates to: " having a plate in front of their head". That iPad is some plate in front of one's head!
Oh, and at events it's plain anti-social because anyone standing behind the person who is taking pictures overhead with their iPad won't be able to see a thing.
I was being sarcastic.....
But that said, yes, I have seen people taking pictures with an ipad..... I do it a lot at work.... I do it at home for Facebook pictures.... And I know a professional photographer who came along on a photo walk last year and shot with an ipad, her pictures were just as interesting to look at as anyone else's. it looked a bit silly, but the results spoke for themselves.
One of the reasons I intend to upgrade soon is to get a camera with wifi.... Take the camera, place near perch where birds stop before they visit the feeder, and remotely control it through the ipad. Upgrading is not always about the sensor, for some it is about features and capabilities.
