Who is using the Google productivity tools like Google Calendar, Gmail, and Documents handling?

I had a friend show it to me this week and then also just saw it on Terry Storch's blog.

It really looks fascinating. Very similar tools to Outlook or Lotus Notes ... plus you get 3 gig of space ... all for free. Any organization or business could run this way and eliminate licensing fees for other products plus reduce their server and storage needs.

And, you "invite" people into your community, giving them access to your Calendar for example. So, I could have my work calendar and all of my co-workers would have access to it but I could also give access to Lisa, Evan, friends, customers, etc.

I remember years ago hearing a prediction that someday all of our computing power would be off-site. It seemed like a ridiculous thought then. But, today, it seems very logical, practical, and economical.
