Using an iMac in tandem with MacBook Air
What is the best way to use an iMac and MacBook Air? Should I use a time machine backup from my iMac to essentially copy the iMac or should I setup two different computers? I originally wanted to have both of them mirror each other but there isn't a way to do so with out paying for it. I know you can use Drop Box but the one file that I want to transfer is too large without paying for extra file store options. What are your thoughts?
Also, up until just recently I had the Air setup from a time machine backup but I ran into issues with the Air having the same names as the iMac [i.e. the Air was labeled iMac (2)].
iMac, OS X Mavericks (10.9.2)
