If your PC has firewire, get yourself a Firewire cable that will fit your PC at one end and has a Firewire 800 connection on the other.
Connect the two machines together, fire up the Mac and, when prompted, answer that you have data to transfer from another computer.
Follow the instructions from there.
Just planning to shift from a pc laptop to a macbook pro. As always, a big concern is how to conveniently transfer files and make sure all of them will work on the new system. Is there a recommended way to move files &/or migrate from a pc laptop to a macbook pro, much like the convenience of the windows transfer function on windows 7 laptops?
