I almost never rinse, but it really comes down to your technique.
When you are washing the windows you are also continually rinsing as you go, to me, - for the most part that is - rinsing is just doubling up on the work you have already done.
Carla, my partner, works with me, now for the most part she rinses after washing...it's how her technique has developed.
If I'm cleaning the lower half of a Georgian sash window for instance, I'll direct a stream of water up towards the top edge of the pane and along the top - without touching the frame - as in this case it isn't so easy to simply wash and go and be sure it will be ok.
Horses for course I guess, as you learn then you will automatically adjust a technique to suit whatever method (rinse on or off and so on) you follow.
