Initially I was thinking that this was a feature apple didn't want to include, but everybody kept asking for it, so they did. Now people are complaining that it isn't any good, but apple never really wanted it in their product to begin with.<p>However, the author points to the unruly tray and how you now have to close applications that you don't think you're actually running. This sounds very similar to OSX to me, where in the tray you've got programs you haven't used for weeks, but they don't close when you shut the window.<p>If apple 'blew it' with the tray, then I'd argue they blew it with the tray on OSX, which I do feel is more of a pain with all it's notifications, and icons for apps I'm not using anymore.
