Just updated to iOS4 and I'm confused about how multitasking works.

It's not true multitasking, but it works perfectly for most people. If an app supports multitasking, iOS can keep APIs and app files in wired RAM. If an app doesn't, it's like a most recent list.
Certain apps perform functions even while not the foremost application.
For instance, Pandora radio plays audio even in the background. Some media sharing apps will continue to upload or download media in the background, and Safari will continue loading a page in the background.
All other functions and apps will simply remain in the RAM, not using CPU, necessarily, and thus not draining battery.
It works almost exactly as a Mac works. After you close all windows in some Mac applications, the app is still loaded in RAM, just not running. Makes 'em faster, yano?
I do notice that intensive apps such as YouTube will hoard all of the RAM and after watching a video or two, Safari and some other apps will have to re-load data to RAM.
Just quit apps you're not using, simple.

It just seems like its more of a hassle than before if I had to keep quiting apps twice. I was afraid that they would remain running and kill battery. I have to say though, I think I'll be missing ProSwitcher/Backgrounder (jailbroken). Though iOS4's multitasking seems like ti should cover some of the stuff.
