Here's one opinion. http://www.williamstites.net/2012/01/05/the-ipad-is-not-considered-an-educational-tool/
Since you're going out of your way to argue against education obtaining a price below $25, I must assume that you have an ulterior motive for this. Either way, discussing it with you further is clearly fruitless.
Those who hold education in more esteem and know the extreme money difficulties under which most schools operate will be looking at ways in which a lower cost can be achieved for Edu once the BOM cost drops through volume production. I have little doubt that it will come.
