I was wondering how the multi-tasking compares on the n9 and the n900. For example, on the n900, if I go to youtube and select some music to listen to, I can then do a ctrl-back arrow which puts that process in the background. I can then start another process like, say, xterm and edit a file while listening to the music from youtube. Can you do the same on the n9? That is, if you use youtube and then swipe back to the apps tray, do you still hear the music playing or does it "freeze" the app? Then to restart you swipe back to the open apps and select it. This latter case would be more or less what android does. Anyways, if the n9 multi-tasks like n900 that would be nice.
