Although the online test drive -- the applications run within a browser and off Microsoft's servers -- may make some wonder if the effort is also a sly way to experiment with delivering Office as a Web application or service, a Microsoft spokesperson rejected the idea. "No. This new online test drive is designed to help people to explore the benefits and enhancements of the 2007 release through their own Web browser without having to download or install the beta 2," she said.
It's somewhat thin-client based, so the installation of a Citrix plugin is required to use the demo. If you use Office and want to see what lies ahead, it's free and probably can't hurt to give it a try. To get setup you visit Microsoft's site.
