Does anyone still use recipe cards?

Lately, I find myself coming full circle and returning to good old fashioned recipe cards. I do occasionally use a recipe book but there are only a few of recipes I do that with. I also have an extensive recipe library in my Paprika app and I have used it for several years. But lately I've been slowly migrating my favorite recipes on 4x6 inch index cards. Recipe cards are how I got started years ago before electronic devices infiltrated our lives. I still have some of my grandmother's handwritten recipe cards and they are some of my most treasured possessions. Do any of you use them?
