Now, there’s a more direct way to sync your calendar. Google Calendar has added CalDAV support – which is the web protocol that iCal uses for calendar data. The current flavor of CalDAV works only with iCal, although other calendar programs support the protocol and will presumably be able to sync at some point.

Google’s instructions for setting up CalDAV on iCal.

I set up the syncing for my principle calendar earlier today, and in a couple minutes (it can take up to 15 minutes) my Google calendar appeared as a separate calendar in iCal. It’s easy, this is a two-way sync, and it updates about eveyr 15 minutes.

It’s not as full-featured as Spanning Sync, however. With SS, you can sync multiple calendars, and designate existing iCal calendars to sync to GCal – the CalDAV creates a new calendar. You can sync multiple calendars with CalDAV but it’s not as straightfoward; that said, it ain’t rocket science.

So, if you use Calgoo or SS or another syncing program, you might want to investigate CalDAV – you don’t have to abandon your chosen program to do so. Or if you’d rather not… carry on!

I experienced some calendar downtime for a couple hours on Monday, but otherwise, I’ve not had trouble. Syncing remains almost immediate between the iPhone and the cloud… around every 15 minutes as far as the computer is concerned.

I’m going to have to pay attention to this over the next couple weeks, and I have no intention of shutting down GCal, but I’m surprised how quickly I’ve taken to the calendar function on MobileMe.

So, to answer the question in the title of the post, not yet, but this bears watching.

I’ll be transitioning to iPhone 3G on July 11th, but not without feeling nostalgic for the way Apple’s first iPhone changed how I view phones. (Is that too Apple-centric for your delicate tastes? Well, bite it, won’t you? Perhaps if I had owned a Blackberry, I’d be just as attached to it. But such was not my fortune. I owned a Treo 700p, which was the worst device – I went through two of them trying to get one that went longer than a couple hours without a reboot – I’ve ever purchased. Your mileage may vary; that was my experience.)

But the updated iPhone is almost secondary to the announcement (expected) of Mobile Me and the new commitment to cloud computing unveiled by Apple. I’m excited about the “push” data functionality that will extend to Mail, Contacts and Calendar. But what I’m really interested to see is how this will impact my current array of “software and cloud.”

At present:

Mail: Exchange via Outlook at work; Gmail and .Mac mainly through a browser, secondarily through Mail.app. iPhone accesses Gmail and .Mac mail through IMAP; doesn’t access Exchange.

Calendar: iCal and GCal, synced using Spanning Sync. At work, Google’s sync software keeps Outlook tuned to my GCal. iPhone gets iCal data through a thin white USB cable.

Contacts: Apple Address Book; Gmail contacts are built based on an occasional import of Address Book contacts. This is highly haphazard. Syncing through Spanning Sync’s new contact sync was marginally successful; syncing through Address Book’s new port to Gmail was successful but a big mess. A messy export from Address Book gets my contacts to Outlook. iPhone gets Address Book data through a thin white USB cable.

How will a more complete syncing experience – a more cohesive experience for all my devices, delivered by Mobile Me, assuming Apple actually delivers it – mean for my setup?

One possible scenario:

Mail: beginning next month, iPhone will work with Microsoft Exchange; OS X will extend Exchange to computers when Snow Leopard is released, apparently. That covers work email; my Gmail path may remain unchanged – IMAP; my Mobile Me email will become more compelling with “push” behind it.

Calendar: Mobile Me will maintain one calendar across my computer, iPhone, Windows PC at work and any other device I connect, potentially replacing Spanning Sync, Google’s sync software, and providing a solid challenge to the relevance of GCal in my workflow. iPhone will sync without the thin white USB cable.

Contacts: Mobile Me will easily maintain one set of contacts across all devices, including Outlook at work. And if I can get syncing with Gmail’s contact database to work the way I want it to, it will take care of Gmail, too. Again, for iPhone, no white cable needed.

What I’ve wanted for myself for a long time was the ability to put all of my stuff in the cloud and have access to it seamlessly across all devices. The first piece of that is relatively easy; the second piece has been problematic. Apple seems to be serious about giving users a new experience with the cloud, and I’ll be watching for indications that this is the case.

With those features working flawlessly, plus revamped photo sharing capabilities, document capabilities, and the doubled storage capacity of Mobile Me, it’s possible the successor to .Mac will bring us closer to Merlin Mann’s cherished .Mac dream, and bind those of us who use it more tightly into the Apple orbit, with a suite of tools that will make, to quote Merlin, your entire digital world safe, fun, ubiquitous, and flawlessly integrated.

In my personal scenario, who are the losers if this strategy works? Google Calendar, potentially Google Docs (at least as far as cloud storage of docs is concerned), Spanning Sync, Google Calendar Sync. I’m hesitant to look at my own patterns and divine some greater scenario in which Google suffers because of Mobile Me; for one thing, Google is so big, does it ever suffer? Second, Apple and Google have a great relationship and I would be surprised if their futures weren’t more tightly intertwined around apps like Google Docs, etc.
