I understand that Win32 iTunes is going to have the best compatibility, but i dont see why if the licensing was established, they couldnt have made the iTMS available to wintel users via the web. It's all powered by webobjects anyway, so why not allow web access as well?
What about all the *NIX(Linux, Unix, BSD, SGI, O/S2, etc) people? they STILL won't be able to access it. Sure its great when its just integrated, but that shouldnt be put ahead of accessibility..
