One of the problems with working with multiple computers is sharing data between them. With the purchase of my 2013 Mac Pro, I've realized that it's relatively easy to transfer information between two thunderbolt-capable Macs. First connect the two with a thunderbolt cable. Next, start the computer from which you want to transfer in "target disk mode". Hit the power button and hold down the "T" key. This will start the computer in target disk mode. The computer which you want to transfer files to should then see this computer as a hard drive and you will have access to all the files. File transfer can then be done over thunderbolt very quickly. Pretty awesome.
