As there is a standard gesture for closing an app i wouldn't call it mandatory. I added one just because i had a menu anyway. But users will probably get used to use the swipe up gesture and use the build in close button fairly quickly.

I personally find a close button aesthetically disrupting when a device has built in ways of closing apps (whether in the form of a swipe for the PlayBook or home buttons for other devices).

I think a close button on playbook app would be about same as a close button on a windows program. Maybe you could put your close button at the very bottom next to the up swipe bezel.

I see it more as a Menu-> Exit which a lot of windows programm have. I agree with John and will probably remove my exit icon if i see that the swipe up->exit is used anyway.

Yeah willyyr. When I was working on my first app with a dropdown menu I had a close button in it but I removed it. If you want a close button that would be the place to put it. About like the file exit menu item in a windows program. But how often do you use that?

I'd guess that a Menu -> Exit mechanism is doomed to disuse, whereas a clear Close/Done/Exit button visible on an app's top page may have a greater chance of being used. In some apps (e.g. many games with a simple top menu) this may be a reasonable way to offer the user an alternative.
Menu->Exit is at least two user actions, which is no better than three other supported mechanisms. It's also app-specific, so I suspect many users just won't remember it. I don't think I'd add a Menu->Exit option, but in some apps I'd use the dedicated Close button.
The system-supported mechanisms, to judge from the Mike Lazaridis demo at CES, are now these:
We have no guarantees any of those will survive to the release, of course.

Another thing to think about is the playbook is a true mutltitasking machine. Why close your app? Swipe left/right to the next app you want to use. Close apps when you start running out of memory. I'd probably have 10 apps open all of the time.

@PBDev, at first my reaction to your post was that I think I'd probably want to close my apps quickly when I was done with them.
Upon further though, however, I suspect what I'd really do is leave things open initially, as I launch new apps, and then from time to time as I'm swiping between apps I'd notice one that I'm pretty much done with and close it then, when I think of it.
If that's true, then I would definitely be making use of one of the swiping techniques more often than I'd reactivate an app just to search for whatever app-specific close button/menu it supports.
Man, we really need to get some real hardware so we can get a better feel for what will constitute "usability" on these things! Or at least a new version of the simulator that has enough capability (e.g. real settings, video, audio, etc) that we can immerse ourselves in it for long enough to find these things out.
