I went to drop off some info to my accountant today and saw they were using Google Calendar. I’m not used it myself and was intrigued by it. They are basically 2 people and with one of them being out at customers most of the time. They said it was really useful and worked well for them. This is first use of this I’ve seen in a small business and the users were pretty happy with it. Google Calendar is in Beta (like many other Google Apps) but we’ll have to see if these services remain free forever? I did mention that Microsoft also has OfficeLive now as well!
