I only use loose minerals on my eyes, too. It would be SO MUCH WORK to get a pencil or fluid liner to do what I can get my minerals to do - I like my liner pushed right into my lashline (I heart my chisel-tipped push brush!) and then feathered out into my lid color (I'll actually foil a tapered line of liner color across my upper eyelid to give it some really bold emphasis). I also like using crazy colors for my liners - I got some super sparkly ones from SheSpace that look really badass, and Meow's Neurotic is smoking as a liner, too!
As for "fallout" - I just brush it away with my fingers. Not that big of a deal.
