The thing about a screen is that it's a tiny window into a wide world. To find anything at all, you must drill down into that myriad of screens to find the one that is relevant. Now, stick a postit on your fridge or on your work screen. Do you need to interact specifically with that note? No. Every time you scan the room, your eyes will connect with that image of that postit and despatch it to your retina and brain. You don't even need to be able to read that postit from where you are. The mere fact that your brain registers its presence, also connects within your brain to know the content of that note, legible at that moment or not. At home we use a paper calendar in the kitchen. That works far better than Google calendar or the iPhone calendar. We see stuff everyday that may be two or three weeks in the future, thus reinforcing the memory of that item such that it never suddenly gets sprung on us that 'Today is the day for X'.
