Hi,
IMHO It seems to me that CodeWeavers has (kindly) already made iTunes 4.x work, and so everyone who voted for this app should move their votes to iTunes 6.0. Apple will probably lock all non 6.x clients out of the music store shortly anyway (they did this in November, but then switched support back on when their sales dropped off sharply) at this point iTunes 4.x will be far less useful, since it won't be able to purchase music. It seems to me that we should try to get 6.0 supported BEFORE this happens, so that everyone can continue to use the music store uninterrupted. Just a kind suggestion : )
Thanks,
Matthew D'Asaro
