At long last, there is CalDAV support in Google Calendar so that it can properly sync with Apple’s iCal. This has taken so long that I’ve pretty much moved completely into using Google Calendar 100%, and don’t even bother opening iCal. In the end, that’s what I believe Google wants — total reliance on web-based apps.
In any case, the announcement was made a few days ago on Google’s Mac Blog. There is a small app that Google is distributing for making the setup process super easy. I’m going to give it a shot and see whether this will get me using iCal again. It certainly would be nice to have this calendar available on my iPhone, especially when I’m somewhere that Google Calendar won’t load due to lack of network connectivity (which seems to happen pretty often for me).
