Interesting, I posted a reply last night defending MLS and it's gone. I'm going to assume it was user error and it just disappeared into the ether when I hit "Submit Reply"
I'm not going to repeat the whole thing as it also might just vanish. But I agree that the originals store is lacking severely. I'm not sure why MLS is the only sports option, that does seem kind of silly but I'm going to assume that MS didn't want to invest in the licensing fees associated with the major sports in the US. That doesn't really inspire confidence when it comes to the Zune platform.
This same attitude is in play in the Apps marketplace. Wheras I don't agree with Apple's draconian app approval process at least they are allowing people in at all.
