“Google’s vision for universal search is to ultimately search across all its content sources, compare and rank all the information in real time, and deliver a single, integrated set of search results that offers users precisely what they are looking for.” - Source: Google Press Release
It is still a mystery whether Big Daddy is doing this for User Experience as it claims or is it a strategy to glue the users with all their services - as a single source of information. Google has been making a clever plan to retain the monopoly position when it comes to Search. Whether it will always be there or not is a debatable topic.
As a user, If I want to read a news story or watch a video, I would like to go there and see for myself. But combining all these services as part of the Search results is certainly going to overwhelm me. When Google introduced Books & Stock quotes on SERPs, it annoyed me.
I guess I have to wait for it to see myself and then comment on it. Hope Big Daddy doesn’t disappoint me any more. 
hello rajesh,
Another good idea that google have come up with, I think this will work very well and give the searchers more but in less steps then before.
Looks good
