I switched to a tablet....a remarkable... and google calendar.  

Once you get into it and start really personalizing it, the online calendar is amazing.  I have several calendars that I can view (at the same time)...dh's work, dd's school, mine and the family calendar. 

I never miss anything.  On my calendar I add all teh things I want to keep track of....vehicle stuff (inspections, registrations), household maintenance, birthdays, anniversaries, heck...even silly stuff like when to bring in the fig trees.  

And because you can set up how it repeats, I don't have to transcribe stuff every year.  It's there...til I take it off.
