this might be a mute point now but all ways do the radio test.
Imagine ur being interviewed on the radio n they say cool whats your website address again?
You say www dot some dried figs n red cabbage on toast with grapes dot co dot uk.
Or
Ebay dot com
Amazon dot com
Facebook dot com
Twitter dot com
Bbc dot com
Google dot com
Bing dot com, been on the radio a lot recently.
That said if its your business name it should be that anyway as thats what ppl will search for.
I personally would remove the www dot before it goes live as its not needed these days and just adds more time saying the name.
This is normally where i pull some statistic out but cant think of any off the top of my head but i would imagine users recall will go up if its not present, or u dont mention it, some useability studies do back something similar with repeated link text and clickability but i personally would leave it off. : )
