I just bought an iMac 20" today. I still have my powerbook 12 for my mobility. I see a future concern though. I know I will be using both macs. My question is: how do i keep these two macs always in sync? 1) safari bookmarks 2) emails 3) more importantly, word documents i create or am presently working on either mac. The iMac is in my bedroom. (Will be using it for occasional photoshop, audio & video work, and of course, some word documents every now and then) The PB is the one I will bring to my office and where probably all my office documents will be done, emails and internet browsing too, (and some photoshop & occasional video perhaps). I want the iMac to be the "master" computer, and the PB, its "slave", if you know what i mean. So, I want that whatever the PB does will be synced to the iMac. Any idea how to do this? Is there a software that does this smoothly?
