Does anyone else feel that in the end, looking at the big picture, software updates in general cause as many if not more problems than they solve? I can't even try to count the number of Windows software updates that caused computers to completely crash and require a complete reinstall, OS X updates that messed up WiFi and performance, iOS updates bricking devices or simply causing old devices to become unsusably slow and laggy, and Java and Flash updates causing security issues.
Yet when a software update does work as it should, it often makes no noticeable difference other than "fixed a small issue affecting 0% of users that caused WiFi performance to drop for a millisecond every leap year in some extremely specific situations that you never knew about".
Sure, iOS 8.0.2 is an update that will make a difference in actually doing something serious, since it fixes what iOS 8.0.1 broke, but then we could've just stayed with iOS 8 all this time without any major problems.
I often fix my parents computers, and the most common problem is that an update ruins something. An automatic Skype update makes it impossible to make Skype calls (go figure), a Windows update makes another program not work, or the computer won't boot, etc... So I've disabled updates entirely, and for the past few years there have been NO PROBLEMS whatsoever.
Sure, maybe an un-patched security hole may, in some circumstances, allow a dedicated hacker to install software to get the computer into a botnet, but that's quite unlikely and even if it does happen, it causes less issues than a computer that won't boot or runs 10 times slower for some reason, because hackers design their software to be stealthy and not ruin a computer, otherwise people would notice. Skype, on the other hand, doesn't care if every single update they release causes their software to break.
