This is similar to having a gaping hole on your desk, where things you use like pens, rulers (that is, applications), can fall through and be lost. Alternatively, if you are writing or drawing and have that same hole under your paper, then when you get to the irregular surface, you can puncture the paper or otherwise frustrate your workflow, like data corruption.
