Many many years ago, I bought an OLPC, actually a pair, one for me, the other they sent to Africa or some other place. I do not remember the year even vaguely. I do remember it had a crank to windup and charge the battery. I bought the two because (from memory) the purpose of the laptop was strictly limited:
* Carry all textbooks on one laptop, instead of having to walk miles to school and back with a heavy backpack.
* Have modern eBook textbooks, not fifth generation hand-me-downs which had been written in a different language for a different country. This was certainly important for indoctrination in local history and culture, but it even applied to math textbooks, whose examples could well use cultural aspects which were literally foreign.
* Be rechargeable with that windup crank for kids whose homes had no electricity.
* Use a screen to read those books instead of having to stop using them after dark or by candles or oil lamps.
In particular, I had never heard that they were meant to teach computer science. It might have been a nice side effect, but I did not think it was any kind of a primary goal. The primary goal was to help young children learn.
