Query: why change now?

I just find it incredibly rude of Microsoft to totally change where all the familiar commands are in these programs, especially in Word. I still haven't figured out how to "save as" instead of "save," and don't really want to waste the time to figure it out. Maybe it is "new and improved," but if you don't want to put time into learning an entirely new system, stick with an older version.
