Well, I don't know whether they count as shipped (cause they really don't get to retailers), but Microsoft is always giving away stuff (XBox-related and PC-related)...
At my college, you'll always find at least several opportunities ever school year to win Mice, Keyboards, handheld stuff, XBoxes (raffles, by attending lectures, etc...), and PC software...
Then there is that generous retailer-related thing where they give massive discount to employees for XBox games/accessories, much more so that Nintendo's "raffle"-style givaways which don't guarantee anything...
I also wonder how much of a bump Microsoft would get if they included these numbers in their statements for shipped consoles/software...
