A load of smaller companies are now using Google Apps for mail, calendar, documents, etc, etc. Most (if not all) programs can be made into web apps these days, and it's good for companies (especially the smaller ones) since people can work from home, or take company laptops without the risk of having data loss, since it's all on a central server.
Oh yeah, and webapps are platform independent which is good if you can't force workers to use a single OS (or don't want to pay license fees for Windows).
