I really only use my viewfinder when there's so much sun that I can't adequately see the LCD anymore. Funny thing is, Canon put so little effort into making a decent viewfinder on my Powershot G7, that when you have the lens fully zoomed in you can see a large part of it in the view finder... 🙄
The alignment of the viewfinder also differs from one camera model to the other. I had a simple Nikon P&S previously where the viewfinder was way off irrespective of kind of picture I was taking. Needless to say I never ended up using it.
