i have a 16:9 lcd and i use only 4:3 skins (aqua!).
i use it cause i can read everything better and also from far away. the font is bigger so i can read my epg's from my sofa (2,5 m!).
Aren't all the circles turned into ovals when you use a 4:3 skin on a 16:9 display?
a little bit! not very important or me! ;-)
