I've got an iphone 4 and backup my contacts to Microsoft Outlook on the PC (as well as icloud). I've just ordered a Macbook Pro so will be ordering a new copy of Microsoft Office for Mac, but as I never use outlook except to back up my contacts I thought I'd save myself £70 ($110) and get the Office version without outlook. Obviously at the moment contact backup won't be a problem as I have it on icloud, but this is no good if one day I decide to upgrade my phone to something other than an iphone. When I've swapped phones in the past it's always been easy to transfer contacts as I just sync whatever phone I have to outlook. Is there a way on Macs (other than icloud), or some free/cheap software, that I can back up my contacts to my computer that I can then access with any phone? Or am I best to just pay the extra £70 to get office with outlook?
