hi i would like to sync my DHD with my Apple mini mac home computer so that i can share photo`s contacts, music & calender how do i do this please i have been told of a few applications i might be able to use, one is DoubleTwist the other is AIRSYNC, have also heard of Dropbox, im new to all this sharing lark and could do with some help, and this seems like the best place to ask.has anyone used any of these apps successfully with a Mac or can perhaps recommend another.also are they easy to install as im not really very technical. regards Tony
