> OLPC was also ruggedised, had replaceable parts and had things like crank charging for areas with no/little power, it was a well thought out machine all around

No, it did not. The crank charger was never supplied commercially, it was purely a marketing tactic. Same as the Potenco Pull-cord generator http://wiki.laptop.org/go/Peripherals/Hand_Crank , http://wiki.laptop.org/go/Peripherals/YoYo

Both were ideas which even basic calculations tell you aren't viable.

In addition, your other claims like "ruggedised", "replaceable parts" contradict what I saw with OLPC XO. I would say the product was a one-off that had almost no consideration for long term reuse. Things like the wifi bunny ears prove that the product was driven more by marketing tacticians rather than reality and cost. Honestly, my opinion is that OLPC was a huge scam to take money from unwitting unsophisticated developing country funders who didn't know any better and waste it in swanky offices in One Cambridge. It was one of the worst options about how to expend public funds.
