The entire purpose
of RAM is to hold stuff for quick access. People just don't seem to realize that empty RAM is useless RAM.
The best analogy would be keeping food in your pantry for quick access. The pantry is RAM. Retrieving food from your pantry is nice and quick, but getting food to the pantry from the store (SD card or other semi-permanent storage) takes time. The optimal thing to do is to keep the pantry filled close to capacity.
Running a task killer is essentially taking the entire contents of your pantry back to the store for a refund, only to have to drive back and re-purchase your food (one meal at a time) when you're ready to eat.
