Google Nexus Tablet selling for cost after just 4 months dev.

It's possible that the 8GB is slightly below "cost", and the 16GB slightly above "cost" so that, based on projected sales breakdown of the two varieties, the range as a whole will break even.

I put "cost" in quotes because working out the unit cost of a single item produced by a large organisation is a complicated accounting exercise with competing methodologies like http://en.wikipedia.org/wiki/Activity-based_costing.
