It's something you hardly ever do. Even if there's been some kind of installation/update that requires a reboot, it tends to be able to trigger that itself (which can cause other pain, but that's for another day).

There are some people who like to shut down their machines, though. I think they haven't forgotten the days when a good reboot once a day was necessary to clear out cobwebs.

That's what I figured. I reboot my Mac when updates require it, and every once in a while if something weird is going on I might reboot it, but by and large my computer has uptime's in the weeks.

Oh so they still have those in Win8. I didn't miss that when I moved to Linux. Reboots for Updates is a broken concept.

I wonder if they're true reboots.

On OS X it's somewhat rare for an update for require a reboot. Often they don't actually reboot the machine but just log you out, perform the update, and then log you back in.

While these updates feel like a reboot since you lose your desktop environment state, you can tell the difference if you're paying close enough attention.

Many are. I get Grub again, and can pick Linux.
