Your smartphone works beautifully as a pocket photographic memory, allowing you to quickly save snapshots of important information you want to use again later. We want to know what useful data you save with your mobile camera.
My favourite? The wish list. I take photos of things I want to buy. If I actually want them, I'll remember the photo and dig it up, look for the product, and fork over my cash. Most of the time I just think I want it but really don't, so it allows me think I'm going to get it and then when I forgot I actually get to save my money.
What's your best trick?
