I have been looking around and found a lot of good info on file back up options but none that specifically answer my question. Also, if this is in the wrong section I apologize. I currently have a PC as my desktop which holds all my "important" data. I recently bought a MBA to replace my ancient laptop and I am eyeing a new iMac soon. Obviously I want all my data, pics, music, and ebooks, to be moved from the PC to my new iMac. What is the easiest way to accomplish this? I currently have a 3TB toshiba external hard drive that I have yet to hook up but would like to use for backing up my data. Also, I want to easily back up my iMac and MBA from time to time and if possible move files from each computer without too much hassle. I don't need to move a lot of files between the computer mainly work documents and pics I upload to the MBA while traveling.
