Oh so your the one that uses it haha. Only kidding. I'm yet to use Windows phone 8 so can't judge but when using windows phone 7 on a limit I found it overly big. For example the fonts and screen menus where huge and took up more space then necessary, and the Nokia screens are good so there's no need to make them that big. That make sense?
I dont think 8 is out in the UK yet unless i missed it. I personally like the big fonts and buttons etc it just makes the phone easily useable. what constitutes more space then necessary? what else would go in the space they take up?
IMO they dont need to cram a ton of stuff on the screen and with the panoramic apps having lots of options etc isn't a problem.
