The main selling point is the excellent access to care, though. When your time is money, you don't want to be bouncing around between three doctors for a month to treat an allergy that prevents you from sleeping. When I was on Awesome Traditional Insurance when I worked at BigCo, it sometimes took over a week to diagnose and treat a simple problem that was preventing me from working. With Qliance, I've gone from call-with-problem to prescription-and-plan-in-hand in under 3 hours. That's a big deal for a freelancer.
I understand there are other organizations around the country functioning on a similar model. You can google Direct Primary Care to find them.
