Nice one NickyColman - My own interest relates to the overall ecosystem link betwixt iOS 5, OS X 10.6 and iCloud. It has become vital to me to have the synergy across the devices and cloud, something I come to expect and use all of the time. I also use one of my Macs to link MobileMe to Google's cloud so that syncing of Mail, Calendar and Contacts is seamless. Change a contact on my Android and it changes in the Apple ecosystem and vice versa. Very powerful and also enabling, new devices pick up all of my essential information in moments and without intervention from me.
