Yes, this is a good strategic move by Microsoft. All of my kids have Google apps accounts that their schools set up for them. They are required to use Google docs, etc., so they can work on stuff at school and at home. I assume that a good portion of those kids will continue to use Google apps as a default for a long time. Similar to a strategy Microsoft used to keep Office a standard: the dirt-cheap student version.

If Microsoft can get schools to use Office 365 instead of Google apps, then $2.5 billion for Minecraft was cheap.
