From my recollections, the OLPC foundation never set out to create the subnotebook. Size was a factor because of the intended audience, but design considerations such as cost and power consumption were much more important. Contrast that to subnotebooks of the era for western markets, which tended to be rather expensive. Those were not the only technical design considerations. Durability, sunlight readable screens, and protecting children from theft and surveillance also come to mind. Very few of those things were factors in the subnotebook market that preceded or followed, except for cost. In all likelihood the OLPC drove the development of other low cost portable computers.
