Incidentally, CCOM isn't in Chicago proper...it's at Midwestern University in Downers Grove, IL, which is a rich (and thus expensive-to-live-in) suburb about forty-five minutes or so away from Chicago if you're driving.
I interviewed at both CCOM and MSUCOM and now I'm going to MSUCOM because 1) the tuition is fairly reasonable; and 2) my family is close by (we live about an hour north of Detroit). However, I don't have a SO at the moment, so that wasn't a consideration for me, although I am much further away from most of my friends from undergrad, at least one of whom is starting at CCOM in August.
MSUCOM's entering class each year is ~80% from the state of Michigan, which is huge and very nice admissions-wise if you're from this state. In addition, their class will be expanding further soon (it actually already did for this coming academic year) because there will supposedly be a big shortage of primary care docs in Michigan five to ten years from now.
However, the fact that this is MSUCOM's goal/agenda has no bearing whatsoever on what you choose as a specialization. I'm actually looking at the academic curriculum for the first two years (Units I and II) as we speak (Unit I stuff can be found at
http://www.com.msu.edu/aa/apinfo/c_gridI.shtml and Unit II stuff at
http://www.com.msu.edu/aa/apinfo/c_gridII.shtml), and out of the 99 total credits you take over said two years, only *two* of them are devoted specifically to family medicine. You can see for yourself from the link posted by jw83 that precisely *zero* clinical rotations in family medicine are required to obtain your medical degree, although that is an option if you want to check it out.
And, well, there you have it.
