I have yet to install microsoft office on my Mac, and I'm 3 months in. Open Office and Google Docs fit 99% of my needs, and the presentation app should fill on of my last remaining gaps... I'll be interested to see how the presentations look - it's hard to give up that beautiful keynote feel

I think Google online office suites still has a long way to go. I've seen a bunch of people tried it, got frustrated and switched back to MS Office. But for basic features it's worth a try For business users, MS Office server also offers a web version of office apps. The major difference is that they are hosted safely inside of the intranet and integrated seamlessly with its enterprise search solution.
