It matters because I don't want an app I that I rarely use to run on its own taking up memory.
They can affect performance by using memory.
If you don't agree so be it, that's your right, I honestly don't care, but just because that's your opinion doesn't mean I have to agree.
I think it's incredibly amusing that so many of you advocate rooting and romming to have complete control of your devices, yet when someone wants to be able to control the app behavior you take issue with it.
After Android 2.2, it having an app cached into the memory will not affect the performance of your device negatively. As far as poorly coded apps, I prefer just to get rid of them altogether.

Because of the way Android is built, if you unload an app manually, Android will either just reload that same app, or find another one to take its place.
