For the last couple of years, people have mostly used a Microsoft browser to use Google websites. I know this is a rather crude statement, but what I mean is that of the two Google has been most successful online while MS continues dominate the desktop and browser market.
Today, Microsoft announced they will be launching a web version of their Office suite. This made me chuckle, as it could lead to a strangely reversed situation where many users use a Google desktop application (Chrome) to use a Microsoft web application.
My guess is that the Office brand name will help to quickly popularize its online exponent, and Chrome might turn out to be the best desktop application to go visit it. Go figure.
