There is tons of great products that came out of Google (be it invented or bought and then improved):
Search, Gmail, Maps, Street View, AdSense, AdWord, DoubleClick, Android,
G is actually no longer a one horse pony (it's more like a carriage with one really strong bull, and a few ponies that are also pulling some weight).
But there are also some less popular G products that are actually amazing (if not the best) and are all a side-product of Search:
Scholar (better than even IEEE's own DB), Patents (no compassion to USPTO's horrible search) and Books (simply an amazing initiative, if only everyone could get paid accordingly).
These last 3 products are ground-breaking for me, even if obscure and not money making (probably).
