The debate turned out well for everyone besides Gingrich, who had been losing the momentum gained by his South Carolina win.
I'm not going to summarize the linked article and video, but here's some additional information:
In one instance, Gingrich mentioned his belief that it is critical that the US invest in a colony on the moon. In response, Romney said "I spent 25 years in business. If I had a business executive come to me and say they wanted to spend a few hundred billion dollars to put a colony on the moon, I'd say, 'You're fired.'" Though Romney and Santorum both agreed that the private sector needs to be more explored in space, Santorum agreed with Romney that it is not a good time for the government to be paying for such an endeavor. He also called the proposal an attempt to get local votes from Florida's space-related constituency, and argued that they candidates should be focused on larger issues than arguing for local votes. Ron Paul did not believe that space exploration should be government funded for anything more than possible defense opportunities.
In response to an episode where Gingrich called Romney the most "anti-immigrant" candidate, Romney responded saying that he found the charge repulsive and that such over-the top-statements have characterized politics for too long. Santorum and Romney then agreed that blocking immigrants form jobs would get them to "self-deport," while Ron Paul though a better economy would keep out illegal immigrants (Though this seems counter-intuitive), but that we should patrol the borders more anyway.

I think that, as recent GOP debates go, this debate was more legitimate than some of the other ones, likely due to the lack of less-popular candidates. I also liked the fact that the candidates were open and willing to criticize the appeals to local votes and extreme statements that have made national political debates and campaigns less... intellectual... than they should be.
Also, I particularly liked Ron Paul's defense of his health status.
