Scott, you are right that starting January 2014, insurance companies cannot individually underwrite based on pre-existing conditions, and they have to maintain a combined or separate pool for all individual and small business enrollees (having a "healthy" low cost pool is prohibited). But, they can adjust your rate based on your age, tobacco use, location, and family size.
So, at least we do not need to worry about specific high-cost diagnoses that have plagued us in the past. The hard part is getting everyone signed up. A poll in my state (California) indicated that about half the people who are eligible for discounted or free rates through the exchange/expanded Medicaid are not aware of it.

I know there will be some missteps along the way, just as there were with Medicare, and Social Security.
