You need it for your documents and files at school/college/university. You store images, files, videos and all sorts of other things on your phones and there is an ever growing need for MORE!


Where do you store data? On a memory stick? On your phone? Do you back up? Where? Can you think of a more efficient way of storing everything? How about on a tiny computer chip embedded in your little finger? Would that work? Is this good or bad - what do you think?
