I would say for the moment it would be worth looking into making it so that the smaller form of the navigation is what's used when normal sized too.
Smallscreen menu must be different from normal one. You cannot just resize the normal one and say it's fine. smallscreen=smartphone and you rarely have a mouse pointer there instead buttons need to be large enough for your fingers.
Also on Chrome 17 the text in the 3 buttons is top aligned now rather than vertically middle aligned.
Bad idea, this way the browser would preload all images on first load and so the site gets slower & traffic increases.
