Eventually I ditched any hopes of syncing with the PC world apart from using the web-based version of dotMac/mobileMe.
Then Google Calendar started supporting the CalDav standard. If you followed the instructions it worked well, but it was not exactly intuitive. It's worked so well, in fact, that it's one of the key reasons I decided to ditch mobileMe altogether (see my article on replacing mobileMe for free here).
So imagine my surprise when I read in Macworld today that Google has introduced a tool called Collaboration that makes syncing your Google Calendars with iCal a snap. If the instructions above were just too daunting, this tool will help you make the switch--and it's VERY painless.
And for my PC-using friends out there, if you've got Outlook 2003 or 2007 you can easily setup syncing with your Google calendars as well.
When the good stuff is free, why pay more?
