Now that Google (NASDAQ: GOOG) has begun to go after Microsoft (NASDAQ: MSFT) Office, International Business Machines (NYSE: IBM) wants a piece of the action as well.

Big Blue will launch a new, free office-like product called Symphony. It will be available on the internet, and it is free.

According to The Wall Street Journal "Symphony is based on software available from Open Office." The same foundation is used for Sun Microsystems (NASDAQ: JAVA) and Google's desktop applications processes. The product also has functions from Notes, a product IBM bought years ago. Notes was almost run out of the market by Microsoft. IBM hopes that the free software application will help it sell more recent versions of Notes, which includes e-mail and instant messaging.

Does the IBM launch matter? Probably not. Nor does the recent upgrade of Google Apps to include software similar to PowerPoint. Microsoft has about 500 million desktop applications running on PCs and the Journal writes the company has "sold 71 million licenses of its latest version of Office in the fiscal year ended June 30." The Office software sells for slightly more than $100.

Getting customers to leave Microsoft, with its huge installed base, is almost impossible.
