Would anyone want to use M$ next to a fast Linux system? and wireless at that. Thats going to eventually open a gate to Viruses and allow them to brick all the OLPC's all in one clean swoop, seeing as they would all be connected through the hash. Now unless this is going to be a special breed of M$, thats not forgetting to close a few back doors and actually has working firewalls and AV, I don't see this going anywhere good.
