The stores often change layouts within a single store and/or have different layouts at each of several stores on purpose. By forcing you to wander around looking for what you want, they're hoping you'll see some additional items you'll be willing to buy on impulse. Club stores (Sams Club and CostCo in the US, for example) are notorious for this practice.

50 years ago? Electrical power IS STILL a huge separator today. Many "developing" countries have unreliable electrical service at best, and often NO electrical service to the poorest of their citizens. Added to all the other problems you said, OLPC should have realised that putting a damn computer in the hands of some country's kids is completely missing the point when the kids have probably no electricity, not even basic healthcare, no sanitation, little or no education, and perhaps barely enough food. Forget the computer ---- there are far bigger problems to solve first.
