Did OLPC have anything to do with this? It seemed more like the asian computer makers thought it would be a good idea to roll out machines their own citizens could afford, since it's a gigantic market.
If OLPC hadn't forced the issue, no one would have cut their manufacturing costs and margins to this level.
Now we can get a 1.6 Ghz laptop with wifi + camera +windows XP for under 200$ (Saw the Acer netbook for 189 the other day!). Frankly, while they were never able to hit their 100$ sweet spot I think the OLPC project has been a massive success.
Heck, we may even be able to attribute the push for the cloud... and cloud based applications running in a browser... to the low powered laptop movement started by the OLPC project.
