If a user can't login to the GUI and doesn't have the dvd on the road with them... how do they do a combo update?
Yep that is a good use for it. Tho unless they've preinstalled it, they're going to require internet access and another computer anyway, so the combo updater is an equally available option.
And if you're going to practice being prepared, a bootable flash drive, or service partition on your internal drive, is a
much smarter way to go.
