Well with your previous comment it is pretty obvious where I was coming from!
Apple doesn't care about how many people have 64-bit processors. They care about how many people have 64-bit OS, they wont dedicate a massive amount of resources to get iTunes running on 64-bit windows if there is only a very small percentage of people using it. Once Microsoft decides to make 64-bit window mainstream Im sure apple will have 100% iTunes support! But if Microsoft wont even support it, what incentive does that give apple (I am referring to the Zune launch)

given just how many 64bit machines are floating around nowadays.
