There's also much less than meets the eye with Google abandoning Exhange ActiveSync. Google Sync is built on Exchange ActiveSync, but it's a proprietary system that's designed to sync mail, calendars, and contacts, as well as provide some EAS services, including security policy enforcement. Google Sync isn't Google's only sync product. For years, Google's been able to sync email with IMAP and sync calendars with CalDAV. On September 28 of this year, Google announced that it was adding CardDAV support for syncing contacts.
Google isn't abandoning its EAS support. Effective Jan. 30, 2013, Google will no longer allow you to set up EAS support on a new device, unless the account you're using is from a Google Apps domain. If you already have Google Sync set up with an existing Google account, you can continue to use Google Sync/EAS on that device for as long as you like.
Hidden in the fine print: The change only makes a difference for Windows Phone and Windows Mobile users. Android users get all the sync they want natively, no intervening software required. iOS users can choose between Google Sync/EAS and IMAP/CalDAV/CardDAV syncing. At the risk of starting a religious war, I would venture to say that many people prefer the latter, and for good reason. Certainly, if Google Sync isn't available for your new iPhone or iPad, IMAP and the DAVs provide a reasonable alternative.
Windows Phone users won't be able to use Google Sync on new devices after Jan. 30, unless they're using an email address that's being run through Google Apps. When you set up a Gmail account on Windows Phone currently, you're given two choices: sync email, or sync email, contacts, and calendar. After Jan. 30, if you set up a Gmail account that isn't part of a Google Apps domain, you won't get the second choice.
But where's the beef? Switching to a Hotmail, er, Outlook.com account gives you EAS, and you can easily use Hotmail to gather your Gmail mail. You can suck your Google contacts and calendar into Outlook.com, too, but it's a one-way street. And you can use Windows 8/Windows RT's Metro People and Calendar apps to keep it all on your tablet, netbook, or desktop.
The only people who will be severely affected by Google's change in EAS policy are new Windows Phone users who have Gmail accounts that aren't part of a Google Apps domain and who want to use Google Calendar or Google Contacts, instead of switching to Outlook.com's Calendar and People apps.
It's a tempest in a teapot, folks. But Google's skillfully turned it into an "up yours, Microsoft" PR moment.
