Ok, you know what I'm saying but you pretend you didn't understand. Beginning with Lion, a file is "always open" in the sense that there's no longer a difference between a file in the disk and a file mapped in memory: Everything you modify in an app is saved in the disk file even if you don't save it, because there's no longer a separation between these two representations.
Such approach is very convenient for phones and tablets, because you're taking notes in a quick way and you want to have a backup of everything you did even if you didn't save it (somebody might call you while you were writing a note, and you don't want to lose that).
However, it's a severe annoyance when using a computer. When I work with a spreadsheet and I'm testing how it works, I don't want to save the modifications I did, because I was just testing it. When I'm viewing
a file with Preview, and I rotate the orientation, I don't want to modify the file, because I was just viewing it --but I want to be able to save it if (and only if) I wish so
. When I'm taking draft notes over a text document, and at the end I realize I want to discard the notes, I want to close the app without saving the changes, etc, etc, etc...
You can say it's easy to lock the file, or to duplicate it, or whatever... No, that's not easy, because it requires you to change your mind: In iOS, the system decides you want to save the file even if you don't want to. You can use a non-intuitive way for avoiding saving it, but it's not straightforward.
If all computer vendors, and all operating systems in the world adopted this new file I/O paradigm from today, it would be reasonable to learn it. But I'm using computers of different vendors everyday, and I'm not going to risk losing a file or modifying a file I don't want to modify, just because I forgot to have the "iPhone mindset" when using the Mac, or the "UNIX mindset" when using Linux. Sorry, I'm not going to risk my files.
Sorry, have a nice time with (Mountain) Lion, but I'm enough with Apple
