The Cobb County one to one laptop initiative has some interesting numbers.
What struck me, other than the scale of the program, is training and support per student works out to about $80 per machine per year. That is about a third of what our local high school spends on Windows support (which is still somewhat broken after spending the money).
One wonders how programs like this will be viewed a few years down the road. I have a suspicion that it is a good thing, but I don't know the field.
