Wrong wrong wrong. You clearly don't understand how the device functions. I can call it multitasking because that's what us tech support advisors call it. We even have a "multitasking" option in our database to log issues that pertain to this feature. So, get over it. It's called multiasking, regardless if that's what is truly is or does. Technically, there is no real "multitasking" application for the device, yet the category is still there.
Good job quoting Apple support articles because it's not like I have access to them on a daily basis.
Clicking the red X closes the window/application. And yes, it's called an application because I'm pretty sure things like safari and itunes are listed under Applications when you open finder. So, point for me - moron.
Also, the list of recently used apps also indicates what apps are still running on the device. Yes, these apps are draining battery, affecting performance and also, in some small manner, use data. So, again, you're wrong.
Plenty of people have their devices freeze up or act weird because they have 30+ apps running in the background. Please don't act like you know what you're talking about. It's one thing to act smart on a forum/community board and it's another to actually work with these products on a daily basis.
