While Google Apps may not be a knockout threat to Microsoft's enterprise business this year, a cloud apps battle continues to brew between the two companies. Google and Microsoft are the forerunners in this competition, but other rivalsare nipping on their heels. Here's a quick look at IBM's Lotus Symphony and Lotus Live, Zoho's suite of cloud apps and OpenOffice.org's offerings.IBMLotus SymphonyLotus Symphony, a set of free productivity tools, includes documents, spreadsheets and presentations. Because it is based on the Open Document Format standard, you're not locked into proprietary file formats, software licensing agreements and upgrades. Unlike Google Docs, however, your files are saved on your desktop\u2014not in the cloud\u2014thus they're only available to you from your computer.[For more, check out CIO.com's cloud app bible: "Cloud App Wars: Microsoft vs. Google."]Lotus Symphony's Documents, Spreadsheets and Presentations tools each include many features similar to what you'd see in Google Docs or Microsoft Office.
