How big a hard drive do I need?

Author's Note

As someone who recently decided to upgrade my hard-drive capacity when buying a laptop, I struggled to justify just how much of the space I use versus how much I wanted. With the ubiquity -- and incredible capacity -- of external hard drives, it seems to me that you should always pay for what you need and only bump up the number ever-so-incrementally for future use. The rest can go on an external hard drive for safe-keeping.
