This is a tricky one. On the one hand, kids need to know about current technology as it is inextricably part of life - I'm currently unemployed and virtually every job requires PC literacy and has an online application form - but on the other, I think that in this, the 'communications age' the convenience and overwhelming disposability of technology is not going to teach kids the value of things.
If you illegally download a movie or MP3 then you are going to attach no value to it, so it becomes throwaway, if you have a free phone upgrade every year, then that too is disposable. If you can contact your friends from anywhere at any time without any human interaction, then maybe relationships of any depth become less important too, on this I'm not sure.
I was a real 'stay indoors' type of kid, glued to my AMIGA A1200 for days on end, but my folks always dragged me out for long walks and visits to country parks and houses, museums and places of interest. Sure at the time I resented it (damn them taking me away from Alien Breed!) but when I hit my late teens I was nothing but grateful for what they did.
I worry that the later generations will have no idea of the value of things, no dirt under the nails so to speak. I already know kids who seem to think hamburgers are spontaneously generated and that potatoes come pre-chipped from the magic white cupboard. It worrys me more that there will be a blank acceptance of technology without a question of how it works.
