I suppose this year is different but what about when you're outside and you want to check your calendar? Do you copy everything to a pocket calendar and risk them going out of sync?
Here's some possible scenarios though:
* If I need to remember when something is going to happen, such as "I'm leaving my house to meet a friend at 4 PM", I can just commit to memory what time it was suppose to be.
* If there's a lot of stuff happening, then I'd make a note on my phone. If the times of events change while I'm out, it doesn't really matter if my calendar at home is out of sync. I'm just going to cross the day off when I get back.
* If I find out a later date will change ("the user group has been moved to Thursdays"), then I'll leave myself a reminder on my phone. Most of the things on my calendar are actually little post-it notes, so I can move things around. I only write things in ink when they will never change, like national holidays that are already scheduled/set in stone.
So far, I haven't really run into any pain points. The drawbacks of paper calendars just aren't enough to overcome the drawbacks of electronic calendars.
