True, this is something of an experiment and may not be the optimal way to educate. At least, not yet. But Xoom tablets are $200 today and the price for tablets continues to fall. In a year or so, there will be e-readers on the market for $20 and many decent tablets will be available for $60 and less. The market is glutted with last-generation tablets and phablets. Something of this nature could provide a second life for these tablets. Xooms in particular are extremely durable and could service children for years.
I would also keep in mind that the development community is probably biased toward hiring new teachers. Again, this just sounds like an experiment.
