@pk: of course you are... ;-)
the creators of pi took strong steps to keeping their device from being another olpc-like thing to either be ignored or hijacked by big businesses like olpc was. in my daughter's school the administration openly admitted they worried about things like the raspberry. because from what they heard about it, the self-taught kids were more knowledgeable about them than most teachers were. so where would their math and science teachers fit in with something like that? that is a question which begs a even bigger question. ;-))
and don't even get me started on what their attitude towards the Khan Academy is.
