For this, I would use the 'smash-together' method. "How many months have contained an experience of a computer breaking on me?" over "How many months have I owned computers?" will give me the probability of the computer breaking in any given month, and then the graph y=(1-pr(break))^x represents the continuous variable "My computer is not broken". This takes about five minutes: it's worth it for cars, computers, homes, smartphones, etc. But you're right, too annoying for smaller cases.
