For starters, "updating" actually is "re-installing." My wife's disk is loaded with iTunes "updates" all over 50 MB. Well, that is a big disk space waste. Doesn't Apple do any cleanup after its updates? No, it doesn't. You are supposed to delete them manually when you are done with them. Since the day it was installed, iTunes insists on installing QuickTime despite the fact that I come across maybe one QuickTime file per month in my daily life. It looks like Apple's media file format has the same kind of market share as its operating system. That is annoying enough, but there is no way around it and I got over it.
Now, comes the insult. The latest iTunes "update" installed Safari on the computer. Safari for those of you who don't know (and if you aren't part of the 6% of computer users with an Apple, you probably don't) is a web browser. So, despite the fact that Windows comes with Internet Explorer and the fact that everyone who is savvy enough to not use Internet Explorer already uses Firefox, Apple has decided to load its browser on every computer that has iTunes. Oh, sure, you can uncheck the box to install Safari, but if you are an attorney, like my wife, instead of a computer person, would you know that Safari is not something that you need for the full iTunes experience? After all, this is an iTunes "update."
