Right - they now have a 64-bit OS, so if all of their apps aren't 64-bit, alarms seem to go off in their brains, regardless of whether they'll ever see any difference between the 32-bit & 64-bit versions of the apps.
I think the issue for people is not that they want 64 bit for no reason. Everybody assumes and usually right so, that with 64bit comes a smoother and faster application.
So with the Snow Kitty being 64bit, why did itunes not get it. It really dosent matter if you have a 10GB library or like me, a nearly 200GB iTunes library. Smoother is smoother and people like, would have liked to see a 64bit itunes.Having said that, iTunes 9 is nice but iTunes 9 64bit would have been nicer.
