She is right that without Negroponte there would be no OLPC, and she is also probably correct that without the OLPC's tremendous "$100 laptop" buzz in 2006, there would be no Asus Eee in 2007, which really kicked off the netbook craze.
Regarding the discussion of whether computers belong in children's hands, I had the opposite reaction: The idea that each child should have their own laptop computer that they carry with them is still a fairly controversial one, IMHO. Negroponte hardly ended the discussion, but he did serve to legitimize/popularize Seymour Papert's earlier Dynabook proposal.
