"A FREE VERSION of Sun Microsystems' StarOffice business productivity suite is now available for download from OpenOffice.org, an open-source developer community sponsored by Sun. "OpenOffice.org 1.0 provides users with a nearly identical software package to Microsoft's Office suite, featuring word processor, spreadsheet and presentation programs, said OpenOffice.org in a statement Wednesday. "The source code from the previous release, StarOffice 5.2, was the code base for both OpenOffice.org 1.0 and StarOffice 6.0, but the two products are both advances over that version. The StarOffice 5.2 software was distributed as a free download prior to the release of 6.0. Sun's desire to capture business customers led it to offer paid support contracts for 6.0, and still allow free downloads of an improved release, OpenOffice.org 1.0, for users who didn't require support or training."
