Hi,
Ok so i understand this move to peace with MS was NOT very enlightening for open source community, but hey you have to do something if your NOT getting closer to your vision.
I'm myself long standing FOSS fan so I respect GPL versions, Linux and all that this movement gave. But You have to fallow the white rabbit To the hole if you want to get your vision from lucid dream to reality 600,000 OLPC is not enough for such good idea. AND I can't blame MS because they are getting more and more open minded. You have to respect that in the way. For ex. they opensourced their silverlight specs for Novell and their mono project. So keep an eye on MS but don't blame them for their monopolistic past. After all smart kids can always dual boot:)
I say YES do it let the children to move forward to their dreams.
