I have black granite with gray variations in my kitchen, too. Love love love them. Yes, smudges show, but I want my countertops to BE clean; not just look clean. I use windex to clean them when I'm having guests. Usually, just wiping down with the dish cloth does the trick, though. Now cleaning my stainless steel toaster is another problem entirely. So glad my fridge isn't stainless... what a mess!
