Pardon my cynicism, but I don't like the idea of choosing a patient you're going to "spend your money on" as a replacement for a basic universal healthcare. Healthcare shouldn't be a popularity contest. As an addition to a normal "basic" healthcare it's fine, but please don't replace existing systems with this stuff.
I urge you to read the announcement. Watsi is going into a different space than before - integrated healthcare (including preventive action) as opposed to their traditional funding a single patient model.
