Just about everybody involved with digital distribution is coy when it comes to sales numbers. Nobody wants to give the game away. But that doesn't stop some - like publishers/online retailers Stardock - from trying to guess!

Stardock boss Brad Wardell says "Our estimation is that Steam - as the current market leader - enjoys approximately 70 percent of the overall digital distribution market with Impulse at 10 percent and all others combined at 20 percent in terms of actual dollars generated per month".

While we have our doubts that Stardock's Impulse service is at #2 (surely Direct2Drive is bigger?), Steam's 70% figure is - if it checks out - both interesting and frightening at the same time. That's about the same level of market domination Apple enjoys in the music player scene.

Quick: name another portable music device that's not an iPod. Off the top of your head. Now tell me how many people you know own an iPod compared to a portable music device that's not an iPod.
