Today's Lotus Symphony has absolutely nothing to do with the Lotus Symphony of yore. It's only connection is the name.
I use Lotus Symphony 2 and prefer it to OO because it is less clumsy under the fingers, but IBM is missing a beat or two in its construction. First, it is unable to open old 1-2-3 files in the WKS, WK3, and WK4 formats. Second, it too slavishly imitates the horrible user interface of Office instead of going back and reviving the very simple, flexible interface and menus of the Lotus 1-2-3 R5 (a program I still use regularly in preference to any other spreadsheet); thus those of us with piles of WK4 files are still stuck. Third, they did not even think about resurrecting Improv, which represented a complete rethink of spreadsheets and how they work.
MS tried to mimic Improv in a release of Excel a decade or so ago, but as usual, missed the point. If anyone knows where the source code of Improv is, they'd do the world a favor by releasing it as Open Source so it could be implemented in modern environments.
