Google vs. Microsoft. Chrome OS vs. Windows. Google search vs. Bing. It’s a battle and it’s only just begun. The two companies have gone head-to-head many times, but this summer things are heating up as they invade each other’s most lucrative markets.

The showdown is definitely creating a lot of buzz. Hiawatha Bray at the Boston Globe recently wrote about it and quoted Dave Girouard, president of Google’s enterprise service division as saying, “Office is a fine product, but it’s hard for me to believe that it defines the way people work in the 21st century.’’ Yesterday, The New York Times ran a piece on how Bing is delivering credibility to Microsoft in the search engine world. So who is the real frontrunner?

Do you agree that the companies will each remain top dog in their respective categories; that Google will continue to own search, while Microsoft dominates computer operating systems?  Will the heated competition serve them both well, or erode market share and create room for more innovative, young disruptors?  Is there room for more than one major player in search and OS?  Will Microsoft’s hilarious Bing commercials help win the world over? 

Should these companies stick with what they’re good at, or will their experimentation benefit us as consumers?  At this point, we’re all questions and no answers.  We’d love to hear your thoughts.
