Integrating Apple services with WP7

Has anybody tried getting @me mail/calendar/contacts working with WP7? And any idea as to how good that works? I will probably get the next nokia/apollo wp7 (unless I'm completely blown away by iphone 5/ios6). But I don't want to give up my iPad and mac and I definitely don't want to use Google's services. Apps and other stuff I could probably re-buy but I need the basic organizing stuff like email/calendar/contacts to work with Apple's services. Anyone has experience with this scenario?
