This may be the small decision that puts Microsoft out of business
Think about it.
Oracle is currently trying to acquire Sun. If that goes through, Oracle will own Open Office, which, combined with Oracle's DB platform and Sun's Java platform, is an across-the-board threat to Microsoft in everything except operating systems - and if Oracle makes all their software UN*X compliant, totally wipes out Microsoft.
All because it's too expensive for a company the size of Microsoft to continue to connect to Oracle databases.
For want of a nail... their kingdom will be lost. Bill better start selling his shares fast if he wants to be able to afford to continue to fund his charity work.
