Sorry, BOM estimates from supply chain analysts are not COGS.Amazon doesn't lose $20 per tablet, they lose around $3 according to

Nobody knows exactly what those figures are. You can't quote one BOM estimate and say that's the correct one versus somebody else's BOM estimate.
BOM estimates are entertaining to look at (most are laughably dismissed by the device manufacturers) but are only relatively within that analyst's history of BOM estimates; they aren't really valid to compare with another.
And unlike sports bookies, BCS computer rankings, Wall Street analyst predictions, etc., there's no way to figure out who is the most accurate since the device manufacturers never reveal actual COGS.
