Hi John,
Unfortunately no settings on the Mac will help the the blurry/greyed/uncrisp text. It is a resolution thing and 1280 x800 on a 15" screen aint going to cut it, need at least 1440 on a 15". I have 1680 x 1050 on my 15.4 laptop and you do have to mess around with settings in the OS and certain programs to enlarge the text and icons also I run Firefox and by hitting Ctrl+ it increases the website font beautifully. Crisp, clear, and black.
