Except the guesses need to be good. I make it a point to avoid criticizing applications for not being power usery enough but there's a line you can draw where it becomes clear that the guesses are too frequent and consuming too much computing power, just to be ignored.

I've seen this a lot with my mother in particular, who is certainly not a power user but knows enough to get by, struggle to use software that's trying too damn hard to guess what she wants, instead of letting her just tell it what she freaking wants.
