I just read that the OLPC now is 75% more expensive than planned. It will be very interesting to see the reactions from the countries who signed up who now will need to cough up 75% more in costs. It is also an adjustment of $25 since only a month ago. It is also interesting that the Intel Classmate PC is only $75 more expensive. It seems to me that the visionary project underestimated challenges of the project.
