When you have to do an update and you want to shutdown the PC (or reboot) but you can't stay in front of him you can't choose before the behavior. Today you have to stay in front of him.
The problem is sometimes when you are upgrading your distro, there is an upgrade failure due to overloaded mirrors.
Steve Langasek (vorlon) suggested in post #16 that in case that update-manager should offer "the opportunity later to try the upgrade again when it's more likely to succeed", i.e. when mirrors are not so saturated with requests.

Not an idea
The ubuntu update manager starts bouncing up and down like a seperate application to notify a user of updates.This makes it an annoying distraction. Further more when applying changes, The progress bar comes in front of what you are working on.
I think it is too hard to import GPG-keys of repositories that you added in the "Software-sources" settings. If you add a ppa there, the key will not automatically be imported causing a failure when trying to install the program in Software Center ("can't install from untrusted source" or sth like that).
In the commandline, it works perfect: add-apt-repository ask you if you are sure to add the ppa and then imports the GPG-key. Also, apt-get asks you if you want to install from an untrusted source, if the key of a program you are about to install is missing.

Won't implement
For various reasons ubuntu automatic updates can fail. For example a laptop is plugged in to power and starts auto updating. It's the suspended and removed from power until it shuts off hard. Now the system is likely broken beyond a novice users ability to fix.
