Apple has released the minimum specs for using the upcoming iCloud service. We already knew that you would need iOS 5 to get all of the features, although iTunes in the Cloud and automatic downloads are already live. But Apple is also making it clear that if you’re using a Mac you’ll need to have OS X 10.7 Lion installed.
That’s not too bad, since Lion will be a $29 upgrade from OS X 10.6 Snow Leopard. But things look a little different on the Windows side.
Apple says iCloud will support Windows Vista or Windows 7. The company also recommends Outlook 2007 or Outlook 2010 for accessing contacts and calendars. In other words, Windows XP users may be out of luck.
I can’t imaging many people who have been holding off on upgrading from Windows XP making the jump just to access iCloud — and it’s a much more expensive jump. Windows 7 upgrade licenses typically run $100 or more.
