The only two services Google offers that I would be truly sorry to lose are Search and GMail. Of course as an advertising platform, regardless of which side your on, it lives and dies on the strength of search. For that matter, GMail has sucked me in because the search is so good. So I guess for me, Google is still just search.
Now if Google+ had come out two years ago with search that actually worked so you could access all past activity, it might have given FB a run for it.
Otherwise, to me Google just has so much money they buy a company a month, see if they can either suck some useful knowledge out of it, or turn it into a big win, and if not, they abandon it. It's more or less an angel investor mentality. Throw a bunch of stuff at the wall and see what sticks.
