I have an aluminum MB w/ 280 gb hdd, and a refurb iMac 1 tb hdd shipping soon. What is the best way to network and/or sync the computers? They both serve as office and personal computers at the moment, but the iMac will be the computer I use primarily for all of my work. Although, the MacBook will come out into the field with me for use at times as well. I assume I should sync my iPhone to the MacBook I have always used to sync it to, correct? I know these may be rudimentary questions, but I've never operated two machines at home. I should mention I back up each machine to two separate LaCie external hard drives. Thank you in advance for your insights.
