My opinion on ObamaCare is that it's highly imperfect (single payer, or some sort of extensive subsidy program like they have in Japan, where costs for various simple treatments are *gasp* very low), but that if it's struck down in its entirety, then this country is not going to try health care reform for at least another 40 years, which is something we can't afford. Keeping the Affordable Care Act does 2 things
1) Makes some super-necessary reforms, namely that insurance can't deny you based on pre-existing conditions, that children can stay on their parents' plans until they're 26 (which in this economy is necessary. It's very likely that i won't be able to afford health insurance on my own at least for another two years)
2) Makes it clear that the government can make a difference on health care legislation, which opens the door towards further reforms
Now, if it is struck down, it will create an atmosphere where reform will be impossible, both because of the legal precedent against the individual mandate (or worse. Who knows what crap Roberts and his neanderthal goons are cooking up?), and because of the example of the immense amounts of political capital that was needed to get even this half-assed measure passed. No-one in the future is going to want to undertake this effort if this one amounts to naught.
It'll make sure American quality-of-life stays behind the rest of the developed world for at least the next half-century.
