hello, ok heres the deal, im getting a 15 powerbook when they finaly update them, which i beleive has a dvi thingy for plugging in new apple monitors. Ive got an ancient (about 10 years old) sony 15 inch bog standard ( sorry i dont know terms very well) monitor. is there anyway i can plug this into my powerbook when i get one as two screens would be a real benefit! thanks!!
