I got the iPhone 4 about a month and half ago and I know that it has the multitasking dock, but I never use it. In fact, the only thing it really does is when I look at it and see all the programs "open" in it it makes me nervous that they are using power unnecessarily. I don't notice any difference with how things work over my iPod Touch or iPad, which haven't ever had multitasking. So is multitasking doing anything for me in the background that I'm not realizing? Is there any reason for me to go in and "clean up" my multitask bar (do I really need Doodle Jump sitting in there?) Do any of you use multitasking in some meaningful way (besides Pandora which is seemingly the main point of multitasking if you listen to Apple haters before multitasking was supported)? Is it helping in some sort of way, maybe to speed up things, that I don't realize? It isn't like I need my iPhone to compile code in the background while I do something else, so what is it doing?
