My computer is almost six years old and strains under the weight of newer versions of programs. Nonetheless, like a sucker, I always give in to curiosity and download the update - and without fail, the updated version taxes my system to the brink of death. Plus, there's inevitably a handful of new insufferable features and/or the absence of once indispensable ones, all which make me yearn for the previous version. And all I really want from my computer is basic and solid functionality. So when Apple takes nice little iTunes 8 and turns it into the swollen behemoth that is iTunes 9, I have to spend the next hour fighting my operating system and its stubbornness in letting me revert back to a previous version. Whereupon I discover that, in the whole 30 minutes that iTunes 9 was on my computer, it decided to take the initiative of tweaking my music library so that iTunes 8 can no longer access it. Most damning was the fact that the green 'zoom' bubble no longer shrank the window down to the mini controller, but rather arbitrarily resized the window and moved it randomly around the screen. And I didn't like the new Music Store. I'm rarely happier with how my computer functions after an update.
