Here is naive question: The problem Theranos is solving can't be that difficult, you just need to take smaller amounts of blood and automate testing. Is anyone else doing this? Seems very promising area. I see that Theranos is facing crazy obstacles to make things work, not 100% sure why can't they produce something instead of nothing.

Statistics stops you. Blood testing is all about statistics. You measure a certain number of things in the blood test, which gives you an idea of how much of the thing you're looking for is in the blood. Some of these things (bacteria, virus, etc) only needs to be in the blood in very low concentrations to be harmful, and to get a good reading you need a larger sample.
