System updates happen about every other month. Some are large but most aren't that big of a deal. It's only when they stack up after several months that they should be annoying. I would usually just have it update later and turn itself off. Game updates are the same, I would skip them, play the game, then update it afterwards.
Of course, now with PS+, my PS3 updates automatically when I'm asleep, so I'm good.
In the amusing department, I knew a guy who bought a PS3 just for the Blu-Ray player. It was several YEARS before he found out it had online functionality. When he got WiFi, he said it took a full day and night to update.
