It is true, Obamacare borrowed some things from Romneycare, most notably the mandate. But other than that there is very little similarity between the two programs. Obamacare is a typical Democrat entitlement program, a huge one size fits all scheme, designed to redistribute wealth, raise taxes, and dramatically increase the size of government. Romneycare was very modest in comparison and did none of those things.

Massachusetts spending on health care was 23% of the state fisc in 2000, and 25% in 2006, but it has climbed to 41% for 2013. source: http://online.wsj.com/articles/SB10001424127887323968304578249694095831444

Romneycare has received federal subsidy, and has caused tax increases. Massachusetts is one state, not fifty, so naturally the size of the programs differs. Aside from the scale of the programs and differences in threshold values, the architecture of the plans is the same.
