Google Calendar is finally here. I've waited over a year for this. I'm happy to say that it's everything I expected it to be... it's a very good and simple shared AJAX calendar. Nothing more, nothing less. There are some bugs, and it's a bit slow on the sharing and finding contacts task, but overall I'm pleased. Actually it's a bit slow all around. I'll review it more plus do some comparisons to other calendars over the weekend.
