The video above (at least one of them) was showing an entire automation line built on Roche technology-- easily an order of magnitude more than 400k. The Cobas 8800 is just a component of that entire line.
Ah ok, that makes more sense. I figured a 100K or so per unit would be cheap the way it has been engineered. That's a whole robotic laboratory and what with the normal price of cleanroom equipment it would be ridiculously cheap if that setup was a few hundred K.
