In the office, syncing appointments is really handy as well. If you are at lunch, your phone will bleep and remind you of a meeting, instead of you not finding you till you get back to your desk when you are allready 10 minutes late.
If all those meetings where set up via outlook in the first place, the whole thing becomes painless
