An interesting question. I actually have the HMO model since this year, but never used it until now. In fact, I might call them tomorrow to ask them.
If I don't forget it.
The "advantage" of the model is that you pay less but can't do "doctor hopping".
I prevents people from seeing multiple doctors for the same illness.
I work in Wiedikon, where SWICA's HMO-center is also located.
So it's not a big problem for me. And I rarely actually have to see a doctor.
Last year, a lot of people changed into these models, so this year the insurance companies had to raise the monthly contributions. I'm sure you got your letter from the health insurance already.
The problem is: health-care is not like meat, where people really eat less when it's more expensive.
While there's the cliche of old people just going to the doctor to have a chat in the waiting room and get to talk to the doctor, the amount spent on this kind of treatment is not significant compared to what e.g. a myocardial infarction and the treatment in the months afterwards ends up costing (50-100k).
I pay 200 per month, the otitis media last year ended up costing some 500 or 700 CHF (including going to the emergency at 02:00 at the weekend and a couple of examinations in the weeks after), which I paid from my franchise.
Switzerland sees some 30000 myocardial infarctions every year, according to this site:

and is expected to spend almost 70 billions in 2012 on healthcare-costs:

Politicians already count it as a success when the increase in costs is not "dramatic" two years in a row.
