I've seen and read of schools investing millions in computers with no tangible results in students' scores, grades, or even elevated interests in learning.

That's because instead of investing millions in computers they should be investing millions in education. Remember: The XO is not a laptop, it is an educational tool.

The big problem is actually teaching something at all, ever, no matter the tools selected for education.

Exactly. If Dvorak doesn't like the idea of sending a truckload of XO's, perhaps he should suggest some other educational gift.

And we should probably insert that famous quote by Amartya Sen:

No substantial famine has ever occurred in any independent and democratic country with a relatively free press.
