sony aren't even pushing digital distribution as much as microsoft, yet they have much more options available, and have probably got the ball rolling sooner than ms.
sony offers full retail ps3 games to download over psn, with a STRICT drm policy that prevents sharing the game on other systems. microsoft doesn't offer a single retail 360 game over xbl. sony were also first to offer ps titles over psn.
microsoft sell hard drives at an extortionate rate with only 2-3 sizes available (20, 60, 120). who would feel confident about digital downloads when they can't even afford the space? sony give the option to fit whatever space you want, at a MUCH cheaper price.
psn uses real currency, not points to price items, to me it adds a little more seriousness to what you're selling.
if you asked the average joe who was really pushing dd with these options, they would probably say psn right now.
