Obamacare increases the burden on employers, and generally prohibits high-deductible health insurance policies that are actually insurance (as opposed to comprehensive policies which cover minor and predictable expenses). It's probably still better than the status quo, but it means we lose the option of going with a plan that's actually good like Wyden-Bennett (http://en.wikipedia.org/wiki/Healthy_Americans_Act).
We still have yet to see what comes of it in 2014. I'm not hopeful, but the foundations have been laid for much worse that produced reasonable results.
