Google Search History and Bookmarks

Google - Search History

So what does this have to offer that del.icio.us doesn't? Well the real value is not in the bookmarking, but in the personalised search engine, that returns results based on previous searches. Now that is cool!.
I think the bookmarking thing still has someway to go as del.icio.us has an obvious head start. But it's made easier, by being able to browse your histroy and rate the pages. Thus fine tuning your search engine and bookmarking pages to return to.
A good move in adding value from an already massively used service of Google's search engine. I'll give it a whirl and see how it goes. But I'm not abandoning the del.icio.us Firefox plugins just yet.
