Don't knock OLPC
"What will they use it for ?", "Who pays for the internet access ?", "Why not just teach basic subsistence farming", "Why would they want one when they're starving ?".
etc. etc.
The mesh wireless network pioneered with the OLPC can use a single internet connection (for example at the local school) and the laptops themselves form a wireless network enabling connection for as far as their combined ranges allow. The information flow from village to village can significantly improve resource management, skills in farming, exchange of goods locally and medical advice - as the children connect on a larger scale, so will the adults.
The OLPC is not a replacement for any help charity can give in terms of food, farming or development - it is supplementary to that. It is focussing on communication and understanding amongst the children. For there to be the political and idealogical solutions required to help developing countries - giving the children the chance to connect to one another, and the skills to find out for themselves the information they need in life - is essential.
The OLPC project is one of real hope, and the disgruntled complaining about other people's charity (one presumes those who complain are not contributing) is deeply unpleasant to see.
