So, Google has started to incorporate Calendar elements into Gmail. The obvious Outlook-ish invitations work:

I love Google calendar, and have switched over, perhaps for ever. The integration with Google Maps is a killer, and the invitation system is boss:

I couldn't get the supposed "auto recognition" of events to work reliably, although Philipp Lenssen at Google Blogoscoped makes it seem easy, unless I specifically used the phrase "can you join me for lunch Friday at 12pm" or the like. Invitations like "can you get on a telcon at 2pm Fri" didn't work. For the moment, that is in beta, for real.
Note over on the left side, I have partitioned my world into a bunch of different calendars, which have different kinds of visibility. I make the Family calendar accessible to my family, but private to anyone else. I will be making the Conferences calendar public, so that anyone can see where I am -- although I think I will rename to something like Stowe's Whereabouts. My pal Greg gave me access to his calendar, and I will be doing that for him, since we work together a lot and basically have no secrets. Work, Work, Work is all the scheduled work stuff, like the endless telcons and meetings. My partitioning, though, I can click various things on and off independently. I would rather have tags, though, so that events could appear in multiple calendars.
So now my desktop calendar, iCalendar, is just a repository with subscriptions to the various calendars at Google. It have set it up to sync every hour, so when I am disconnected from the web I have a working copy. In this way, this model of calendaring is more like blogging than ever. I publish my calendar on the web (perhaps with protections), and I and others subscribe using a calendar feed reader -- in this case iCalendar. And of course, iSync syncs the local copy at iCalendar to my phone (which Google doesn't do, yet), which is just like putting a podcast onto my iPod from the RSS feed reader.

I'd be careful before you rely on GC if you use it to invite people to meetings. People with Apple Mail just get a .ics attachment to a pretty barebones email message and folks with Outlook see the raw text file, not a message with Accept/Decline options.

Hmmm. I will have to try that out, and rag Google about it.

Please do... I wsa going to do a review, but given that it would be literally my first post...
A bit more info - Apple Mail is the Panther version and looks like this. Which is a ton better than how it shows in Outlook. Meanwhile, 30Boxes gets it right.

I am sure you know about the SMS interface to Google Calendar that can keep you in touch when there is no wifi around. ( http://ekive.blogspot.com/2006/05/update-google-calendar-on-road.html) for the basic info on the SMS interface. Try sending a gCal Quick Add syntax SMS message to 48368. Eg. "Meet Mark at Café Montmartre tomorrow at 1pm"
Since the gCal-iCal subscription interface is a read-only link the SMS functions are a nice way around the limitation – if you have an unlimited text messaging plan.
