Why would any of you allow an infant near a computer be it the XO or any laptop. And for those with children two or older why haven't you explained to them how to handle one. When i was a child and had access to my first computer my father explained to me what to do and what not to do with them. And ever since then i have treated all technology with absolute respect. Don't just give a child an expensive piece of technology and hope they wont destroy it. I'm sitting at a public computer right now and have to punch the space bar between each word i type because its stuck. And this is in a college lab. This is something 18-25 have been using and they still destroy it.
Instead of blaming the makers for "poor materials" why don't you take the time and educate your children on proper computer care. Don't leave them alone with it and expect the best. Would you leave your child with a domesticated lion because its "supposed" to be safe?
As for overseas and the recipients of those laptops, I'm sure they have had little problems with this. They are being given a computer which was previously only in their wildest imagination. I'm sure that even in the worst of conditions they are taking better care of their XO's then your children are. Why? Because if you were poor or computers were in-accessible and someone came to give you one, then you would take care of it like it was a child. Once again i say Would you leave your child(computer) with a domesticated lion(wild child) because its "supposed" to be safe?
P.S. Why are half of you scolding OLPC for sending out "flawed" machines. I don't see any of you building computers to send to those who cant afford them. You should be happy that your investment is actually doing something good for those that don't have.
And yes i believe that you should have access to replacement parts at little to no costs. But when you do this replacement i certainly hope you don't allow your child to treat it the same way again.
