It didn't kickstart netbooks, which predate OLPC XO by a decade and were far less experimental designs.
There were older subnotebooks of various kinds but "netbooks" by that name are usually associated with small Atom-based machines that Intel was pushing partly in response to OLPC hype. See, e.g., this article from 2009. https://web.archive.org/web/20110130085835/http://blogs.comp...
Netbooks are usually considered to have started in 2007 with the OLPC and eeepc: https://en.wikipedia.org/wiki/Netbook
It did kickstart the "netbook" form factor, which ended up replacing most OLPC use cases. So not a total failure from a technology standpoint, like Juicero and Theranos were. But it is a bit of a poster child for everything that's wrong with the MIT Media Lab.
