I don't really see the value with SuMO... it's just a monitor, not an updater. So the user still needs to do the actual updating.

I've been happily using PatchMyPC for a while now. Fully featured with scheduling, lots of options, etc. Supported program list has most of what you'd expect (all major browsers, Acrobat, 7Zip, Revo Uninstaller etc etc). Not a huge database of programs (around 300) but works quietly and reliably in the background.
