So far I've kept all the Lion features turned on until now, as I wanted to give the new OS a chance to convince me to drop my old habits and learn the "Lion way" of doing things. However, as for Resume, I found myself either closing all windows before quitting apps (which is a lot of extra steps), or finding it annoying that old and unwanted windows reopen when opening a given app. For this reason, I turned the feature off. But I'm sure Apple put that feature in for a reason, so my question is: what's the use of Resume? Why would someone want to have old documents automatically reopen? If I'm working with Pages, the chance that I will reopen the same document I was working on yesterday is very low. I would find it easier to just go to wherever I saved the file and double click it. Even if I do want to work on the same document, I would not remember whether that was the last document I had open when I quit Pages, so choosing to just open Pages would still leave me uncertain about whether it will reopen the right document. Can anyone give specific examples of when they have found this feature useful?
