Migrating files to a MacBook Air

One of the tasks facing the new owner of a MacBook Air is migrating files from the old machine. With the MacBook Air's wireless-based connectivity, this may not be as quick and easy as of old.

'elbert', a member of PhilMUG (Philippine Macintosh Users Group), wanted to move stuff from his old 12" PowerBook to his new MacBook Air but he had some problems. As he explains in the PhilMUG forum:

The challenge:

To get my new MBA up and running as if it was my old computer, as simply and as quickly as possible.

The limitations:

My old Powerbook has more data than will fit into the MBA, with around 100GB worth of data inside my Home folder alone.

I don't have a Wireless N router, nor is the PowerBook wireless N capable. So the wireless Migration Assistant, a new feature made just because of the MBA, is going to be a really long process

The MBA has no FireWire port, and I would've liked to use Target Disk Mode as well as my trusty old FireWire drive to move stuff around, as well as to install my fave apps.

The answer:

Well... read elbert's ingenious solution on the PhilMug forum.
