If you want to get a flavour of iOS7 without going the beta route then log into Apple iCloud beta because it has be iOS7’d.
Mail, Calendar, Contacts, Notes and Reminders have all had the makeover. Pages, Numbers and Keynote are still in iOS6 mode and i have say even at this simple menu level already look old fashioned and tired.

An interesting touch is that when on the current iCloud you want to swap you click the cloud icon in the top left of the window and then you go back to the main menu. In beta you get text thus Actually it looks like an image and when you click it it give you a drop-down menus with the other locations.
There has been a lot of heated argument over Apple new design and whilst i have been largely in favour of it and run the beta’s on a phone and a pad the difference in the iCloud design has thrown it more into relief for me and i think Apple is on to a winner.
