Oh I am sure the same or similar keyboard shortcuts were always there - it is just as you said - when there were simpler ways to point and click we didn't need them. I am one who doesn't mind clicking when the clicks are obvious, and so tend to do that rather than memorize 1,000 shortcut combinations even though keystrokes are generally faster once you know them. On the other hand, make me do more than a couple of clicks to get somewhere and I'll take the time to memorize the keystrokes.
I actually am not bothered as much as apparently some people here are by what has been referred to as "bloat" on iTunes. I'm actually not sure I'd want to see functions "separated" into multiple apps. As long as I'm familiar with where to go and what to do within it, I don't mind iTunes being the one-stop-shopping for all media - in fact I think it's a good thing, in much the same way that it is a good thing that the iPhone contains all the technology that used to require a storage room to hold.
My only gripe is that they keep making it a moving target. I don't like them changing where things go and how they are accessed after I've already gotten familiar with the user interface. Improving is one thing, but "rearranging the chairs on the Titanic" as you put it is quite another. And unless they are adding new features (which they aren't), then that is all they are doing with releases such as this latest one.
As for the inferiority of the more current Pages releases....yes, it's a deal. I won't get you started if you don't get me started. I don't consider the new releases improvements either (to put it mildly) and so it wouldn't take much to GET me started!
