I love John Lennon and what he stood for; I love OLPCs and what they stand for. Combining them in an OLPC commercial is not a completely misguided move, but the execution is a bit off. If it's not the impersonator doing a cheesy Lennon accent, then it's the lazy way they connected the man and the movement.
Still, thinking of the song "Imagine" will always give me goosebumps.
Watch it, and tell me what you think.
