I don't think technology is evil and it's part of our lives and going to have a bigger impact on our children's likes, they use iPads at my child's school for example.
But it's no replacement for parenting, neither is tv etc. I have three children my twins are 2 and can both use the iPad, they enjoy it but they only play with it for about 30 minutes once a week, they have a broad range of things like do and enjoy, including books, imaginary play, outside play, drawing etc.
However i Also have a 4 year old, who spend a great deal of time on the iPad, he has autism amongst other things, and only just realising how severe things are with him, he has many issues, he doesn't like other children, even his brothers, (he loves them but they are too loud and he lashes out constantly at them when they get too close). He usually can't deal with noise or normal play, he doesn't have the concentration for books, drawing etc. school, is a nightmare and I was yesterday told by the head that realistically we are probably looking at special schools as Sam is so severe. He has very violent meltdowns and is constantly hyper sensitive to everything, however the iPad, or games chill him out, it's not something i like and I feel extremely judged that people think it's bad parenting, but it helps him so much and he learns so much, I've spoken to so many professionals, and they all say go with it. So he comes home from school in a state (he finishes at 1030 as that's how long they can cope with him) and he gets the iPad for an hour or two, he is then much calmer and usually needs more tech time about dinner time as he is just over stimulated and stressed out by then again, and then after an hour he is fine, evenings are better as the twins are asleep and he is able to have quiet time, but for us the iPad is a life saver.
I cannot ever see the twins wanting that amount of time, the have so many interests and abilities that my 4 year old doesn't, they will sit and cuddle, they can watch tv (he cannot cope with tv, or rarely anyway) they love to play with me or each other.
I think those parents who used computers games, tv etc to babysit their kids will use iPads to babysit their kids, I think those who use resources sensibly will continue to do so, but for parents of special needs kids, and it seems fairly common in ASD children, iPads can be such an amazing resource, you can get apps that help the children verbalise how they feel, which is much more hardly than cards etc.
