Yup. This is it in my humble opinion. The tipping point for XO - One Laptop Per Child. It's going to run on Windows now. OLPC also has a Board member on AALF as just announced (but not yet on the Web site.) So the business model now will make sense for real across the board, across multiple countries (read: US schools) ubiquitous use of One Laptop Per Child.
This is what we've been waiting for. We will likely see large increases in 1-to-1 implementations soon and not just using XO computers.
