At present I use google calendars and sync to both my mac and iPad/iPhone via exchange. I don't want to give up using google as I share calendars with other google calendar users. At present I end up with two versions of my google calendars on my iOS devices: one synced in near real time wirelessly via exchange and the other syncing to iCal when I plug in to the mac (but that only happens occasionally). Irritatingly the non-real-time versions have taken the colours from the mac (that I want to use) leaving dull browns for the iOS. When iCloud goes live, can I get iCloud to sync with google and then unify the look and feel of all my calendars via iCloud or will I be forced to continue with the current works but not quite right system I currently use?
