Post your comments for Google Calendar now supports CalDAV and iCal here

[W_Loring]

I've been using this feature for a while now, and it works great. I've got work, home and iPod calendars all synched together. The new setup tool they have makes it easier than it was when I set it up the first time.
But how do I access the Address Book Google sync feature you mention? I'd like to have my home and work address books synchronized.

Ok, I'll bite. How do I sync my address book with Google? I don't have that option in Address Book's preferences.
Apparently, this option is available only if you've connected an iPhone or iPod Touch to your computer. The workaround I've seen online is to change the "Family ID" in ~/Library/Preferences/com.apple.iPod.plist to 10001.
I have a 60gb 5G iPod. Would there be any unintended consequences of changing that value?

Okay, I found the Google doc describing syncing with Address book, but when I looked at my Address book app, there was no Google option! I'm running 10.5.5, so it should be there, right? Is it because I don't have an iPhone?

iCal has supported syncing with Google Calendars for a while via CalDAV, at least the past few months I've been using it. Has something changed with respect to Google's side of thing?
In Address Book, you add your Google Calendars into Preferences under the Accounts tab. They've been read & write for me, not just read-only.

Will these calendars also sync with my iPhone?
I see my GCal in iCal, but I don't see my GCal in my iPhone Calendar.

I've been using this for months; I'm not sure why they decided to make an announcement today. (Here's a DaringFireball post from August: http://daringfirebal.../2008/08/iphoneicalcaldav )
It works great, except for one huge issue: if you use MobileMe to sync your iPhone, the CalDAV calendars won't show up on it. Apparently iCal doesn't propagate info between CalDAV accounts and iSync. This is pretty much a deal-killer for me, since I'd have to give up wireless syncing.
So instead I shelled out $25 for BusySync, which has its own mechanism for syncing Google calendars to iCal. And then iCal happily syncs these to MobileMe, which syncs to the iPhone.

I wish that Google Calendar would allow you to subscribe to CalDAV calendars. We have a CalDAV calendar on our Leopard OS X Server. In order to get my work calendar to be read/write on my Google Calendar, I do multiple AppleScript syncs of iCal events. Spanning Sync is a good option for the money.

Sorry, but for me this tool is still useless. I have subscribed to 5 calendars of my friends in Google. I synced with BusySync. All worked perfectly! (Today it still has 40% discount on MacUpdate.com). I made iCal backup, removed these calendars in iCal, disabled BusySync, ran Collaboration application, and surely it presented me the list of all calendars in my Google account. I selected three of them, but... only two were added to iCal. Tried again - no success. Calendar's name is "TED & GC" Probably "&" sign to blame or two spaces in the name? I don't know. I restored iCal from the backup, enabled BusySync and I am happy again.
By the way previously Google Calendars didn't support To Do lists. Didn't check if they have added this feature or not. One thing you should know before you unplug .Mac account and switch to Google.

Still stuck between a rock and a hard place...
Address Book <-> Google Sync would be great, if the stupid Google application would not insist on adding "suggested contacts" (those I wrote a single mail to) to the list automatically; and there is no option to turn that cr@p off.
Google does not know anything about to do items. Mobile Me knows them, but there is no way to get them onto the iPhone.
To overcome the to do issue (which is much more important to me than the calendar) I use an additional Remember the Milk account, which is great. Unfortunately I can only have these items in iCal, if I subscribe to my own to do items as a public calendar. This is a) read-only, I can see to dos in iCal but have to open Safari (or the RTM dashboard widget) to tick them off; b) to dos with a due date become all-day events (nonsense) and to dos with a due time become events with one hour duration (even more nonsense). If I now want to have these to dos sync to the iPhone (and also birthdays and subscribed holidays), I have to disable push syncing of calendars, as the iPhone will otherwise not show any of those.
To make it even better - I still need my Toodledo subscription to have syncing notes... yawn.
So, here I am - using four services and paying for three of them; and still I cannot come up with an easy and satisfactory solution. All I would need is push (or frequent) syncing of notes, to dos and all calendars (including subscribed ones). I want to see them on all devices and be able to edit them on all devices. So far I really fail to see the benefit of the CalDAV standard... Incompatible and non-sensical data orphanages I had before that.

[dreyfus]

P.S. After checking it out - there also seems to be a fundamental difference to Spanning Sync... It will also publish iCal calendars to Google - the Google tool does only sync the Google calendar. So if you want to see your iCal alendar entries in Google calendar, you still need to use Spanning Sync or publish your iCal calendars and add them to Google Calendar manually and read-only... not quite the same?

As it turns out, there are quite a few important differences between Google's CalDAV support and Spanning Sync, some of which have been noted in the comments here. I've written a blog post describing the differences we think will affect the most people::

The inability to have this process work with MobileMe is a deal-breaker for me. Synced CalDav cals do not get pushed to the iPhone. Lame.
