The "bangs" make all the difference. Just this morning I used !ups <tracking number> to track a package. I use !w (wikipedia), !gm (google maps), !gi (google images), !yt (youtube) and !a (amazon) all the time. Less often I use !so (stack overflow), !gsc (google scholar), and others. Sometimes I even use !g (google) or !b (bing) if the search results are inadequate. But that's very rare for me.
