    So, I am curious as to how to end/close an app you don't want any longer in your "App Manager." Everytime Steve opened a new app, it would be added to the manager, but what is the point if I now have to scroll through 20-30+ apps to get to another one??? Maybe of you push and hold on the icon a menu will come and ask if you want to close it. :shrug:

    I'm sure there will be a way, but that had me scratching my head during the keynote.

    Any one else catch that?

    Gizmodo posted a video that shows if you hold an app in the multitasking dock (as you would hold an app to move it), a red delete symbol appears in the upper left, which upon tapping it, closes the app.

    Which by any other name is a task manager. If it gives you a list of running apps (or icons for running apps) and lets you choose from them or close them it's a task manager.

    That's ok. I won't fault Steve for slamming those competitors' task managers like that abominable thing in Pocket PC where you had to go about 7 clicks deep in control panel to close running apps.

    I would say Apple has done this as nicely as webOS only they left out the previews of running apps and handcuffed background apps to a handful of "officially supported" things they can do in the background.

    Nonetheless this is a huge step forward for the iPhone/iPod Touch/iPad and I'm glad to see it happen. My only question is will I spring for a 3G iPod Touch or live without multitasking when I get OS 4? I really don't like having to wait until November for this on iPad but perhaps Apple will relent and give us a Finder by then as well.

    Doesn't this contradict what Steve said about not having to worry about closing apps in multitasking?

    I'm still a little unsure about whether the apps in the multitasking dock are all actually open, or just the last apps you have used. Its weird since its not full multitasking, but just using certain APIs. An example would be the API that lets you finish a downloading something, would the icon for that app then dissapear from the multitasking dock once the download is finished?

    I doubt it would disappear. It really doesn't matter if it's still "open" as I'm guessing the app state gets suspended to the fast ROM. That could only be an issue if you had a huge amount of apps open.

    Video BTW (it's the first one)

    Separate 'windows'?

    maybe i should've posted this as a new topic, but with this new multi-tasking system, will we be allowed to have multiple windows on the screen at the same time (ex. aim window and Pages both showing up on the screen..)? I assume not, but was curious....personally i think they should do things differently for the iPad and have an Expose like interface for it to switch between apps.

    But if one never closes any apps, you could have a huge amount of apps open pretty quickly. I think Apple probably has a solution to these things, but I just don't think they explained it very well. I'm hoping some people using the developers copy will be able to fully explain exactly how the multi-tasking works.

    Here is how it works in a nutshell. Every app you open appears in the app switching dock in the order that it was used, regardless of whether it supports a background task or not. This might sound pointless but the good thing is that it makes it much easier when you are trying to switch between a couple apps that you are currently working in, since they will be the first things in the dock. Although this list gets long (not sure exactly how long), it shouldn't matter because a) the recently used things are at the front and b) none of them are actually running in the background unless they support a specific background task. For apps with no background task, tapping on them in the app switcher dock is exactly the same thing as tapping on them on the home screen, and switching away from an app like this is exactly the same as returning to the home screen while using it- i.e. the app fully quits.

    So the only type of app that you have to think twice about quitting yourself are the ones that actually do something in the background, and even those shouldn't be using any CPU time or RAM unless they are actually doing something. So keeping Pandora on the app switching dock doesn't matter unless you are actually listening to songs with it, and keeping Skype open uses essentially no resources unless a call comes in, so the only reason to remove skype from the switching dock is so that you don't receive any more calls.

    Good explanation. I was confused about what exactly those apps would be doing in the background and it makes sense for Apple to only allow certain tasks, not running in background using full resources.

    Agree. Thanks admanimal. I sort of had this all in my brain, but it's nice to see it written out so comprehensively...

    Yeah, that's exactly why they wrote the APIs. Minimize, classify and compartmentalize.

    No problem. Another thing I forgot to mention is that the potentially large number of things in the switching dock doesn't entirely matter either, because let's say you want to stop Skype from getting calls but you opened it 100 apps ago, so it might be pretty far back in the dock (again I'm not entirely sure how it how many things it can hold or where it puts apps with actual background tasks). Well, all you have to do is open Skype from the home screen, and then you can either tell it directly to stop looking for calls (if the app is designed to allow that) or once you go back to the home screen, Skype will now be #1 in the dock again, and you can easily close it from there.

    While people say it does, it really doesn't. You don't have to remove anything from the "task manager" The last app ran shows up at the top of the list. If an app like pandora runs in the background it will run until you hit the pause button inside the app. If you want you can hold down on it and hit the minus button but it is not necessary. That is my understanding of it.

    Yea it is kind of strange, they basically copied the Android multi tasking, but on Android there is no task manager, you just use the icons in the app drawer to open the programs and when you close them they do the same thing that he is trying to do with the iPhone. I don't really see the point of the app manager. It basically runs contradictory to his emphasis that if you see a task manager they have failed. He is essentially saying he failed lol
