I bought my HDTV back when I got my 360, so I've been widescreen for about 5 years now. Currently I have a 42" Sharp, so the hud seems REALLY big to me, but as I said, it's more the positioning than anything else. It'd be nice to be able to move it like you can in some fighting games, or set the opacity like you can in the Fallout games.
And thanks for the welcome.
