The entire US Department of the Interior (~71k employees) switched to gmail this year. It seems to have gone pretty well. The most common complaint I've heard is that gmail doesn't support the custom smiley faces that Lotus did. The inbox size vastly increased (500MB => 30GB) which makes the record keeping much easier, just never delete anything. Before we had to empty our mail into offline archives. Everyone still uses office for word processing and spreadsheets. The online storage is nice for sharing files though.
