One of the things I love about Google Calendar is that it requires no desktop component. Sure, you can sync it with Outlook, but not everyone needs or wants a program like that just to manage appointments.
Indeed, more and more people prefer to keep their calendars on their mobile phones, just as they do their address books.
If you do use Outlook, you’ve probably already configured it to sync with your phone. If not, or if, like me, you’re trying to migrate away from that unwieldy beast, look no further than Google Sync–a free service that syncs mobile phones with Google Calendar.
And not just Google Calendar, but also Google Contacts and Gmail. The service works with BlackBerry, iPhone, and Nokia S60 devices. (Why not Android? Because Google’s mobile OS already syncs with the various Google services, natch. As for the Palm Pre and Pixi, they can sync with Google right out of the box.)
