I'm sorry, but the iPad is not a toy, you and many others may use it as one but that was not what it was designed for, hence why it it not easily made child safe.
If it was designed to be a toy then it would have child safe features.
You're trying to use it as something it wasn't designed to do, hence you will never find an easy or perfect solution to your problem...a bit like trying use a Ferrari to go on a camping holiday for a family of 4, probably not impossible but certainly not easy.
So yes it's do-able for sure, but it's never going to be easy and I think there are other far easier solutions to provide out children with learning tools and an introduction to modern technology without worrying about their exposure.
that's one of the more absurd analogies i've read on these forums, i'll give you that.
The iPad can certainly be a useful tool, no doubt, but it is most certainly a toy for what I would guess a sizable percentage of the people that own it, if not the majority.
for one thing, iOS is not yet a "real" OS. Just look at the benchmarks of even the older lower end macs relative to the newer ipads. I know benchmarks don't really mean all that much, but the point is that the ipad simply isn't going to be a fully functioning tool for a good chunk of people in the work force. It's a great productivity device, it can be a great work device depending on what you can do - but it's still largely a toy.
as it were, when you get right down to it, i imagine most people with ferarri's are using them as toys in their own right.
