Simple enough isn't it? They don't benefit now from using it over Safari. They benefit from it just as a promise from MS that they won't screw up the web just to sell more Windows PCs. As long as it's relatively easy to obtain IE for Mac, it's not a useful tool to sabotage the standards in a platform lock-in grab. However, I agree with you that it seems totally unrealistic to expect MS to do this. Not because they're evil, but just because why bother?
