InfoWorld did a good analysis of MS Office alternatives (Slideshow here). They picked couple of vendors from the cloud (Zoho and Google) and couple from the Open Source world (IBM and OpenOffice) and did some analysis to see if they stand any chance against MS Office. Full article is available here. Here is the summary.
Bottom Line:The good news is, the applications are improving at a very rapid pace. If you have noticed, its been a while that we rolled out a new app. The focus lately has been more on integration between apps and enhancements to the existing ones. In the longer term, we think cloud based productivity suites can go far beyond desktop software. We’ll see this happen over the next year or two.
If you’re ready to embrace the SaaS future, then Zoho could be the productivity suite you’ve been waiting for. Zoho can provide both personal productivity and business back-end applications, and with Google Gears, you can keep working on documents even if you can’t find the Internet. Zoho is the only suite here that you could easily use to run a complete business. It’s also the only one that can run virtually all the Excel macros you might have developed
While InfoWorld looked at Word Processor, Spreadsheet and Presentation apps, the productivity suite goes beyond these three (Wiki, Email etc are others). Also, you’ll need more apps to run your business than a productivity suite. In the bigger picture, we are trying to build a suite of apps to run your business. As we often say, we want to be your IT Department.
