Nice going, WD! Just days after rolling out your 500GB laptop drive (and by "rolling out," we mean "shipping), you've already found the courage to add a few half-terabyte units to your My Passport lines. Starting today, consumers can snap up the My Passport Elite or My Passport Essential in a 500GB flavor, both of which still weigh in at under 7-ounces and are available now. Prices? Try $199.99 for the 500GB Essential, $219.99 for the 500GB Elite.
