Microsoft did it exactly right if you assume popup notifications are necessary. I firmly believe that popup notifications are unnecessary and distracting, and that's why I prefer the "notification system" of OS X (red badges in the dock). These are a standard. Growl and menu bar status icons etc are just useless cruft introduced by developers who don't want to adhere to the standard. I could care less if my OS notifies me that it discovered a new input device, or that someone sent me an email labelled "urgent", or whatever.
Of course, OS X is not as clean and notification-free as I'd like it to be: It annoys me every other week or so with some useless software update, and every 10 days it complains that I didn't plug in the backup drive for some time.
Now, it might be possible to configure and disable all these notifications, but I just don't want to bother. I want my computer to act on my command, and in my eyes there is almost no excuse for putting up an unexpected notification or alert or dialog for anything.
