question about multitasking in Lumia Black update

[akashoak]

in the description about lumia black update ..i read thi-
"Multi-tasking

At long last you're able to view all your open apps and, in one fell swoop, close them all at once too. This is a great option for saving power by stopping background apps where previously you'd have to hit back a million times and close everything manually if you wanted to close the first app opened. Now you can also cherry pick which ones to close and which to leave open - ideal if you want to keep a map handy but not the browser window you used to find the location. Take note Apple, this is something every operating system should offer by now."

can anyone who has 1520 tell me in detail what this feature is and will it be coming to lumia 820??..does it mean like tap 'X' button million times or just a gestures to close all apps.?

Except that it doesn't save any power, because there are no background apps. The apps on that list are not using any CPU cycles, as they have been suspended, with the exception of location aware apps and background audio apps (Here Maps, Pandora, for example). This is nothing more than a fix for a psychological problem.

Microsoft themselves made this semi-messy by using the term "background tasks" for the periodic tasks that the OS allows. This lets users think that some apps are running when not on-screen AND it hides the true nature of these apps as periodic/short-term update-oriented tasks.
