One laptop per child seems to be a great idea and may prove beneficial in the long run for the betterment of education for children. OLPC proudly announced that OLPC XO BTest-2 laptops are here for the future of children and would help to grow adaptability and as well as increase education patterns.
A spokes person at the OLPC stated:

The hardware is continuing beta test for the electronics, beta test of the new screen (this time with a diffuser improving it further) and touch pad. The industrial design is only somewhat improved from BTest-1; most of the learning from BTest-1 on mechanical improvements could not be incorporated in time for BTest-2 and so BTest-3 will be significantly more rugged than BTest-1 or BTest-2.

I personally think it to be a great idea towards the upliftment of child education program and would impart a tremendous boost and impetus in regards to the same.
