IE7 test
----------
Line height is cutting off the baseline in the footer links, and it is displaced above center (sorry centre.. I even write in html now!). e.g tails on the y's

I never like to see header links underlined, I'd also consider a stronger font-weight.
Search input text again line-height issues with text vertical alignment.
Possibly change the black on white text for grey eg #ccc. Too much contrast.
Otherwise ok.
