Specifically they're patenting graceful shutdown of a graphical windowing environment, with a series of prompts to ask the user if they are sure that they want to terminate processes that cannot be gracefully stopped.
All of it seems blindingly obvious, but then it also doesn't look like a claim against any non-Windows OS would last 10 seconds in a court, as there are a ton of clearly Windows-specific claims.
Actually, I read the patent differently. They seem to be claiming that a series of prompts is slow to the user, and that they've invented a more efficient and faster system.
1) Non-GUI applications (or applications without a window) should be terminated automatically
2) Applications with a top window can veto, but when they do the other applications are removed from the screen, so that the user can focus on the application veto-ing.
3) Users can be presented with a "Shut Down Now" button, to force the shutdown, ignoring any application vetoes.
Also, remember the description is not part of the patent, only the claims section is. As far as I see, the claims are OS-agnostic.
I don't see that differently from what other graphical OS do; of course there are minor differences but both macosx and gnome (didn't check other linux GUIs) have something similar.
I'm not saying that they didn't copy it from windows, but I think the features were there before microsoft filed this patent (2005).
The flowchart seems to describe the current Windows 7 shutdown sequence. As much as I hate to say it: if this is so obvious, why hasn't any other operating system implemented it?
Admittedly the parent post is somewhat fanboyish, but it's true that the macbook (and imac) sleep functions are light years ahead of most PC laptops. They sleep very quickly on closing the lid, and resume fast too... I've never found sleep to be as effective on Dells given to me by work.
Avoiding reboots in definitely preferred. I've heard very good things about Mac's sleep speeds, but I have a home built PC and Lenovo ThinkPad that do ok. They take around 5-10 seconds to go from in or out of sleep which is fast enough that I don't think about it and I usually only reboot to install Microsoft Updates, which is a different story.
