Why do I find Dropbox useful? As my parents progress in age, their proficiency with electronics diminishes. Their TV’s get more complicated and they are not as capable of remembering complex sequences. Every time my parents are forced to upgrade their tech (e.g. a dead TV or a new satellite receiver that causes a hardware refresh) I get them to give me the make and model of the new equipment. I download the manuals to PDF format and put them in Dropbox. With the Dropbox iPhone app, I can pull up the manuals anywhere. Inevitably, I get a phone call requesting how to use a TV or make it do something it did previously when I’m not at home or near a PC. I also have their DSL modem manual as well as a manual for troubleshooting their home network (i.e. router + DSL modem) complete with pictures and diagrams I made. This comes in handy when my brother needs to drop by and play remote tech support.
I wonder if my use case for Dropbox is unusual.
