I wouldn't mind washing windows if they looked good when I was done.

7. For just a few windows a crumpled up newspaper is ok...

But for a bunch of em, a squeegee is much quicker and easier. The trick is this: Also carry a clean rag with you. Begin by wiping your squeegee clean with the rag. Then use the tip of the squeegee to wipe the very top edge of the window clean (about 1/4 inch strip) after you have sprayed the window and used the sponge side of the squeegee. Wipe your squeegee clean again, then pull straight down from top to bottom. Wipe squeegee clean once again and repeat, slightly overlapping strokes about 2 inches and making sure to wipe squeegee clean after each stroke (change rag once in awhile if it gets too dirty.) On the outside you may be able to get away with just hosing them down after using sponge side - if not, at least they will come cleaner when u go back over them with the squeegee method.
