I think the Mac app store thing could be a good thing, as finding new apps on the Google is an exercise in slaying SEO dragons, and the various sites that try to catalog Mac apps range from worthless to disappointing.

It's not like the app store will prevent people from downloading and installing apps from other places (at least not yet -- If they ever did, or if they ever tried to do some daft "warning: this app isn't from the app store and might eat your children" thing, that's a different story.) But, assuming this is just another way to get apps, I don't have a problem with adding the app store to OS X.

I am curious -- they said they'll host free apps, too -- is there a fee for that, or do they take 30% of nothing?
