are you saying that all $35M came from Rwanda? and only got them 100,000 laptops?
they probably spent ~$200,000 or so on the 100,000 laptops for Rwanda (probably a bit more to account for infrastructure pieces)
the $35M is probably the entire budget for OLPC for the year (and in 2007 they were not distributing many laptops, they only hit mass production in october 2007)
where is your evidence that the laptops that were sent there have been misappropriated? if they didn't want them they wouldn't have spent the effort to work with the OLPC organization to get them, train teachers, and distribute them.
OLPC doesn't just load a crate with laptops, put them on the boat/plane and then declare success. a deployment team works on-site, with the teachers and watches that the laptops are being distributed to the kids. they also continue to watch after that, if for no other reason that they are looking for success stories to post, but also to help worth through problems.
your attitude that OLPC must be evil is doing a huge disservice to the people with the OLPC project that are on the ground in the countries working to make things succeed.
