In addition to the physical punishment aspect, the battery life of the two systems are miles apart with the Classmate being a mere 4hrs, while the XO 10+. In situations with limited power, this is going to be a huge difference. I would argue that situations where power is not limited (such as richer areas of Brazil), the Wintel offering will be fine-- more electrical power = more processing power. In fact, if they can run the content offerings of OLPC (basically a python-based environment), the goals of all organizations will be met-- hardware sales + very nice educational software. If OLPC can survive then next year or two, the market will stratify into those who have the resources to run Wintel, and those who really need the extra benefits of the OLPC (special casing, cloud networking, power management etc).
