Could be the way font-smoothing for reverse text works on iPad screens and how 
text (characters) hook to the underlying pixel grid. It is almost certainly 
less visible at higher resolution (iPhone).
On my desktop mac (webkit and gecko browsers), the reverse text appears 
slightly 'fatter' than the black-on-white text.
