I just want non-volatile storage. Give me a hard drive that I can read and write to. Use it for to-do lists, or grocery lists. Instead of physically reading a book with my eyes just upload it to my drive and peruse it at my leisure inside my own head. Recipes go there. Even if it’s text-only I can think of a million uses for it. Add the ability to store and retrieve images or videos and it gets even better. My memory isn’t that great and the sheer increase in quality of life that it could give me would be astronomical.
