A good roundup article highlighting the various alternatives in market to Office 2010. Lotus Symphony scores 3rd after Office itself and SoftMaker Office 2010 (never heard of this).
Don't let the name fool you. IBM's Lotus Symphony suite has almost nothing to do with the earlier incarnations of the Lotus Symphony suite -- it's now a rebranded spin-off of OpenOffice.org, with a heavily reworked interface courtesy of IBM's programmers. It also features only three applications from the OpenOffice.org suite, but they're the ones that matter: word processor, spreadsheet, and presentations.Link: InfoWorld: Microsoft Office 2010 takes on all comers >
Launch Symphony and you'd scarcely know you were dealing with anything derived from OpenOffice.org at all. The look of the program is markedly different and, in my opinion, substantially more attractive.
