- When there is an update available a small icon in the panel flashes. I attend to it when I want to (by clicking on the icon). When the updates run, they are downloaded (from a local repo) and applied in the background - I can check on their progress but don't have to intervene. No restart is required.
- Hey, there are security risks. My computer does need to be updated to keep it safe. If you believe otherwise, you're being naive or an idiot.
- My update manager can be told to check for updates on a daily, weekly or monthly basis. Each update is graded from 1 -> 5, where 1 is a critical security fix and 5 is a feature enhancement. I can select to be told about only level 1 updates, or any any level. I have complete granular control over which updates I install (tick or untick).
Given that updating software on any networked computer is a necessary evil, I'm not sure how much more user-friendly it could be?
