When i first switched over from PC last year I had this same mentality but then I noticed that when you open webpages full screen you get a bunch of white blank space on each side with nothing on it.... And now it makes sense to me how apple designed this feature. if you click on the little green + button you'll have the page resized to fit the content on the webpage and get rid of the excess space on the sides, and now I love it. Gives me extra space on my desktop with my internet window not taking up the whole screen. Anyhow it's an ongoing debate here on this forum but give it a shot maybe you'll like it. I was on the other side of the debate but switched over after a little while of trying it the Apple way.
