So, the long awaited Google Calendar is here! Using http://calendar.google.com/ I was able to log in with my gmail account and away I went. After a little use, it seems pretty slick. Everything I need in a calendar program. Here is the rundown, that I have seen so far.
There are options for Day,Week, Month, Custom and Agenda view.
There is a printable view option that creates a pdf of your current view.
Adding Events is very simple by clicking on the time slot or the Create Event button
A very slick "Quick Add" which takes a sentance and makes it into an event. For an exmaple "Date Night with Chrissy 6:00pm tonight" created an event
There are plenty of recoccuring event options
I don't have any friends on Google cal yet, but there seem to be lots of options for sharing calendars. There are also options for XML and ICAL links for both public and private calendars. (I'll use this for my ipod!)
Event reminders, New invitations, Changed invitations, Cancelled invitations, Invitation replies, Daily agenda can be sent via Email or SMS, Events can also have popups (if you are in calendar)
Overall, It looks like Goolge has created a simple, slick and powerful app, akin to Gmail. I look forward to using it more.
